View Full Version : Question for those of you with 20" Rims

04-14-2002, 11:54 AM
How many SCs actually have 20s?
What size are you rolling on (like 20X8.5s or 20X9) and do your tires rub your wheel wells on turns?
I am thinking about getting 20s and need the scoop on how rims that big will ride on a SC...
let me know.

Hey bro glad to see ur man enough for 20's they look SWEET! IM runnin a 90 sc with 1.5" eibachs and 20x8.5 Alba Blaze wheels front and back. My tire size is nitto nt-555 245/35/20 I recommend this tire also, I have had them a year now and they look brand new still, and Im no sunday driver!!!
As for rubbing....NONE,ZERO,ZIP!! DONT LET PEOPLE TELL U U CANT FIT 20'S ON A BIRD! Those people dont know @#%$. I had so many people tell me they wouldnt fit but they were wrong! The only place the tire is close is on the front where the inside of the tire is next to the upper A-arm but this moves with the tire so there is no rubbing!! IM hoping to airbag my car soon and it looks like I wont need much modification to fit those tires even when the car is on the ground.

hope this helps u out Im glad to see more people with 20's on a bird cause its the sweetest lookin thing around


90 sc black on black leather 5- speed k&n freeeflow exhaust and 20"dubs!!!!

can't say that i have 20's (yet) but my bird is dropped 2" and i don't see any problems. i'm debating between 19's and 20's right now, only because the rims i want aren't made bigger than 19". otherwise, it would be 20's for sure.

swoop, scott m (bagged89) has a pic of a bagged bird with 20's on it on his website. i guess he had to do some tubbing in the rear to get the car to lay out. the tires hit on the inside of the wheel well due to the width. something to keep in mind when you do your airbags. btw, i had those same wheels only 18" and they are sweet.

Swoop, what is your e-mail addy?
do you got aol IM?

i got a 1.5 drop on my LX with the Xenon F/X kit and a set of 18" Enkie's. While not as drastic as the 20's I do have to endure alot more then average. Since I live in the Colorado Rockies, I have alot more elevations to contend with. Other then having to slow way down alot, I would see no problems with 20"s... actually, i have hit some pretty hard core speed bumps when i wasn't paying attention... as fast as 50. not one problem.

04-16-2002, 07:41 PM
I just recently ordered some 18x8.5, but now that I see 20's can be fit on my bird, I'm real anxious to get those. I've called a few places, and they all said that no one makes 20's in 5x4.25, even the Alba Blaze. Do you guys have some sort of lug conversion kit? I'd like to get the Elite Impellers but I think they're only for FWD? I'm confused... Any help ASAP would be greatly appreciated.. I'd like to cancel my order for my 18's if I can get 20's.. Thanks guys,

You can convert the 4.25 to 4.50 fairly easily. Check this link:

ok, the front sounds pretty easy, however, the rear sounds like a pain in the butt.. it was kind of confusing as far as what modifications need to be done. could i just install the 5x4.5 hubs, and install the following brake kit:
www.discbrakesrus.com/mak...tm#newkits (http://www.discbrakesrus.com/make/ford/mustang.htm#newkits)

it says the kit comes with two rear end "flange brackets"... is that all i would need, or would modification/fabrication to the caliper brackets still be necessary? Thanks..

even though the tbirds are rwd, they still use a fwd wheel. so any fwd wheel will fit assuming the bolt pattern, offset, and backspacing are correct.

you could also use adapters. however, they will make your wheels stick out approx 3/4"-1".

i change the bolt pattern on mine to 5X4.5 and it was fairly simple. the front is just a matter of replacing the hubs with 94+ hubs and boring the rotor out slightly to fit the new rotor. for the rear, i just redrilled the hub, took out the old studs, and put new ones in the newly drilled holes. you can also use mustang cobra hubs for the year which would have the correct new pattern. those have to be pressed in.

04-17-2002, 06:52 PM
Yeah, I think I'll use the Cobra Hubs for the rear. When you say they have to be "pressed in" what do you mean exactly? My friend works at an automotive shop, but I don't think they have a hydraulic press... Do they need to be pressed onto the car, or pressed onto something that can be removed (so I don't have to take the whole car to the machine shop)?

Also, what's the backspace/offset that I'm going to need with the new hubs? I heard something about how they stick out a little further than the SC hubs? Thanks,


04-17-2002, 08:18 PM
you don't have to take the whole car. you can simply take off the spindle. the old hub will need to be pressed out and the new on pressed in. if you don't have access to an arbor press, swing by one of the local mechanic shops, they will likely have one.

btw, you will more than likely have to buy the cobra hubs brand new so they may get pricey.

i'm not aware of the front hubs sticking out any further, and i don't know about the rears.

04-17-2002, 08:30 PM
Well, looks like I won't be doing the conversion after all.. I called today to cancel my order for my 18x8.5"s and they said they are specially made order by order and they already started mine... they said it'd be a 10% fee to cancel the order... Oh well, the whole 20's project sounded too expensive/involved for me right now anyway... :D

Thanks for all the help... someday i'll be "rollin' on dubs" hehe...

Hey. I need to know what you and others are doing for a skid plate? I cracked my oilpan and would like to fab one but wonder where would be a good place to bolt it to under the car.

Cuz im gonna slap my cut springs back on for fun and don't want to do another oilpan swap .:)


04-18-2002, 03:20 PM
the skid plate on my '89 is welded to the front crossmember. it is 8"x12" . 12" in the long direction, it just cantilevers off the crossmember. its 1/4" thick. It hits road dots and drags when i let the air out and its held on fine.

Cool Thanks.

This is a pic of my buddies Accord it is bagged with 18's. Actually he has the air cannisters on it.


04-18-2002, 07:47 PM
Dang that TBird with those 20s-SHO looks very different. I dont know if its the pic or the look. But it looks like a Caprice or something. I dont know if I like it or not. Maybe its the wheels? Dunno..I got a friend with 20s- Check his Tbird @ hometown.aol.com/tyteasstbird (http://hometown.aol.com/tyteasstbird)
-it has bags too

you mean HAD air, that bird is juiced now. He trying to sell his air stuff that was from a lincoln. here is a piece of the hydro system


04-18-2002, 08:06 PM
Oh ok-didnt know...

04-19-2002, 12:51 AM
that white bird with the 20's is so phat. i would love to have my bird layed out like that. it almost makes me want to take off all my gfx and what not. i think it looks kinda wierd because it is so clean. ther are no gfx or any exterior pieces that stand out.

if those are 20's on that blue tbird, then i am going to have to go bigger. they only look like 18's or so. i'm assuming that car didnt have to have any tub work done for the bags. those gfx take away alot of the potential drop. i have the same front on mine with the stock sc side skirts and the front sits lower than the sides. on that car, the sides are much lower than the front.

scott, you mentioned that car had air ride parts form a lincoln. do you know what parts specifically? i was considering using the front bags from a mark, and then regular firestone's for the rear. this would save alot of fabricating and money assuming they would fit.

04-19-2002, 02:47 AM
I was looking for 20's, but I haven't been able to find all that much... there's the alba blaze, a few kmc's... i really liked the elite "impeller" but it turns out the only 20's they come in are 20x10 for trucks... :( guess it's 18's for me for now...


04-30-2002, 02:00 AM
Hey hey...

I just got some info on some 20"s that I've been wanting to get... They're the Driv Mach 5.. they're 20x8.5" with +45 Offset... you guys think i'll be able to fit these with my 1.5" Eibach Pro Kit? I just sent the company an e-mail asking for a package price, but I wasn't sure what size tires... 245/35/20 or 255/35/20? One of the guys at a local tire/wheel place (Les Schwab) told be that 245's won't fit on an 8.5" wide wheel... Any help would be appreciated... I need to know soon so I can cancel my order for my 18"s if these will fit... Thanks...

Driv Mach 5's (http://www.etoptires.com/Driv/mach_5.jpg)


04-30-2002, 02:16 AM
won't fit...a 245 tire is suitable for a 8-10" wheel with 8.5" being the ideal. also, the diameter of the 245/35 is 26.9" where as the stock 225/60/16 is 26.6". so, with a difference of .3" i doubt you will have any trouble.

04-30-2002, 02:33 AM
i should've figured the guy didn't know what he was talking about... what about the offset? the wheels i want are +45, i know the bigger the wheel you get, the more offset you need, right? you think these will work? i saw on one of the previous posts, someone had the 20x8.5 alba blaze, and those have a backspacing of +42 i believe... thanks for the speedy reply!


04-30-2002, 07:54 PM
I'm not sure I like the white bird w/ 20's. WAAAY too ricy for me - but that's mostly due to the style of rims. The blue one looks ok - still kinda ricy w/ the wings, but overall looks A LOT better than the white one. The blue one looks mustangish w/ the hood. I'm not trying to be a dick, it's just MY opinion. I personally like the corbra wheels and a smooth looking gx kit. Steve

those are the smallest 20 inch tire made, perfect fit for your wheel and car. tell the guy at les schwab to eat it. kmc makes a ton of killer wheels for our cars, you should check a few out. pirelli and nitto make the 245/35, and the nitto's are super hard to come by. i work at discount tire and have a hell of a time finding he nitto tires. but either will work. go talk to the local discount tire guys and see what they can do for you. if they tell you it wont work, tell them to call me @ store inw-01. go for the dubs! i've had 18's and now 17's on my car, while i liek teh ride, the look is very tempting.

05-01-2002, 12:11 AM
don't forget Kumho, a decent tire for the price. also KMC last i checked only made 5 wheels with our pattern. wait 4 now the Nemesis is discontinued. i think they were the evolution, guido, nemesis, gnome, tramp. i think that was it. i got my stuff at america tire company and they did a price match for it. i was very happy with them.


05-01-2002, 01:15 AM
I guess the Driv Mach 5's aren't made in any Ford bolt-pattern... I went down to america tire and had them double check, and I guess the website I saw them on was wrong... Guess it's still my 18's... I'm still waiting for them, but I think they should look good once I get them on...

05-01-2002, 06:24 PM
You can get 20's at www.discounttiredirect.com or by going by a local discount tires. I've been contemplating with the 17x9 cobra r's or some 20's.

05-02-2002, 03:13 AM
i've seen the rozzi's they have a america tire co... i wasn't really impressed with them for the price... got quoted about $3500 for wheels and nitto 555 tires... i'm still waiting on my 18's... it's been about 2.5 weeks since i ordered them, called the place today, and they said they were getting plated, and it'd be another week before they got them.. :(


05-02-2002, 09:23 PM
kmc does make a few wheels for our cars, to me 4-5 is a lot, considering most manufacturers dont do @#%$ for it. thats sweet how americas tire co matched, thats what discount tire co is out on the west coast, since discount tire center has a trademark or something. it's nice having the power to match, that way when someone comes in with a quote from somewhere else, pep-boys mostly around here, we hack the hell out of everything and hook the customer up with a massive deal. what'd you pay for the wheels and tires anyway??

05-03-2002, 12:02 AM
$1886 wheels, tires (kumho), locks, and thats it, no road hazard or anything extra like that. i suauly don't have tires more than a year anyway. bad camber.
