does anyone know what size this car would take ? i want 18's on the front assuming it would be the same as a camaro , but the rear could take a wider wheel . i was thinking 20x10, any help would be great . i am buying a stock car and lowering it and bolting up wheels , not fender rolling or fab work i want to do ? possibly airride !

any pics would be great !

You can run a pair of 18x8's with 4.5" backspace and 20x10's with 5.5" backspace,easily.

Jason if you can find a copy of winter 04chevelle special magazine - same as Camaro Performers - there are 2 cars in there with 18s and 20s - a mild custom monochromanic red 72 and a very stock black 71. It depends on what look your after. If you want all wheels and rubber band tires 18x8 with 255/35/18s and 20x10s with 275/35-20s. If you want a little more tire side wall 245 or 255/40-18s front - 295/40-20s rear. If you want lots of tire 245 or 255-45-18s front - 275/45-20s rear. Sorry I don't have a scanner or I would send them to you. Good Luck with your project - Jack

Yes,I am sure about the backspacing figures. If you need more wheel & tire input,spend some time over at Team Chevelle instead of here.(Camaro Central)

I was wondering if anyone here has seen 20" rims on the front of a 1971 Chevelle. I am wanting to put some on, but I have no idea what tire size I would need to clear my steering and fenders. Any response would be appreciated. Thanks.

72 with 20's. Not the best looking wheels but non-the-less.

Thanks for the response, from looking at the photos I don't think the front rim would fit. I have Hotchkis 500 lb lowered springs and wheel well turning clearance will be a problem.

Here some of the 70-72 Chevelles I pulled from my collection of pics. I know some sizes on some of the cars so if you see one you like let me know. They range from 17s to 22s. I also have like 3 or 4 Chevelle special issue mags which have quite a few in there if you want me to scan a few I can. Let me know.

Hi,
I am new here and I just bought a 71 Chevelle convert. I want to run some big wheels but I also like the car to look good and run some nice springs do you have any pictures of a chevelle with 20's that does not have air bags or do all chevelles with 20's have air bags.
I drive a 95 impala SS with 20's and I like them allot in handling and in looks. I really don't like the look of 18's and 20's looks funny to me. I use to work in a hot rod shop and I have owned a few roadsters and sleds but I never liked air bags.
Any input or advise would help me a great deal
I have a set of billet spec.18's Vintec's but they came off my 92 Chevy truck and I think they have the wrong bolt pattern. it does have two bolt patterns but i have not looked at them but my work with spacers???
Thanks

I scanned the attached a couple pictures of one Chevelle(white one) with 20s without air bags and one with 20s and 18s (which I like better). I personally think that with this size of wheel you need to lower the car substantially. Also you will need to upgrade the brakes to help stop the additional rotating mass. Not to many performance tires are offered in a 20, thats why I'm probably going to go with 18s or 19s. Hope this helps.

Thanks for the pictures it helps me a bit more. The disk brake part is no biggie there are a lot of kits out there. I think I am leaning more towards the Wilwood set up I have used them on Harleys and hot rods.

I like the look of the white 70 it looks good to me. I want it to handle good so I am sure I will do all of the rear end mods along with A arms in the front.

I don’t need a race car I wouldn't mind one but then I would have to build a different car. I would build another 32 roadster. I wanted more of something that the wife can also drive and that it isn't a new car its also a plus that she loves Chevelles & Camaro's

Just curious but why do you need to trim the lip? Wrong backspacing?

I dont want to steal your thread but could someone post some more pics of 68s and 69s?

The look of that red 68 is just super nice, I'd like mine to be like that when done. (I'll go for black though)
Are those TT 2's

No offense intended,Brian,but 18" and 19" front wheels & tires can increase cornering performance. If that's not the case,why do so many ultra high performance cars use them? Vipers and C6 Corvettes use 19" rear wheels,too. 22's might be over the top but I really doubt most of us could tell a huge difference between 19's and 20's,all else being equal.

Just curious but why do you need to trim the lip? Wrong backspacing? no, aftermarket quarters with huge lips on them. its maybe the wrong backspacing but i doubt i could of found anything that would fit without cutting. the price im gonna have to pay for a 22x10 i guess :bananna2:

my car isn't the "rule-book" pro-tour car. i have global west upper-lower tubular control arms, B-body spindles, 13.5 wilwood brakes in the front, air-ride shockwaves, and a 1 1/4 sway bar. i mean i guess i could of kept in the QA-1 coil overs i took out for the air-ride but the shockwaves seem nicer then the coil overs as far as handling anyway. im gonna try to see what 19s and 22s will do as far as handling. i mean i guess i coulda bolted some 18s on it and been like everyone else, but hey if someone didn't try to turn the page, we would all still be stuck in pro-street style stuff. :enguard:

im not going to argue with you. im stupid for putting bigger rims on my car, this i know. as far as degrading the car, i don't agree with you. im not really worried about YOUR opinion as far as I like what i have. i feel that your degrading me by talking about my car when all i did was posted a picture when someone asked for it. i have a 68 firebird for pro-touring "theme". why did i spend the money on the suspention? once again it is MY car. MY large rims will do exactly what i want them to, and im sure i can still outhandle most cars on the road. but once again, what do I know becouse im just a degrading part of this site. :hmm:

BAZ67, I am new here but you should do your home work a little better!!

Please read I am courious what you wil say about this one……

CAR & DRIVER
Porsche Carrera GT
suspension—unequal-length control arms all around with race-car-style, pushrod-activated coil-overs mounted to the structure—will yield very little to a lowly road undulation, and because the structure will not bend even to the degree that stiff steel or aluminum cars will, all the movement is transferred to your unrestrained body bits. Unlike that of many super sports cars, or even mere sports cars, though, the Carrera GT's ride is not harsh. It doesn't feel nervous or skittish on imperfect roads. And unlike other fat-tired sports cars (the Porsche wears 265/35ZR-19 Michelins up front and 335/30ZR-20s in back), the GT doesn't suffer from bump steer. Truck troughs and crowned roads are beneath its consideration.

OH! by the way I have owned a STREET ROD TOO !! 32 Roadster.. more of a race car than a Camaro.. kinda like a Indy car ... big wheels, No fenders, no top, no AC/heater

I'm guessing the backspacing is inadequate,Slow. However,before I stick my foot in my mouth,what car are you trying to fit 22" wheels on?

BTW,Do you really like the Air Ride Shockwaves? I'm seriously thinking about pulling off my QA1 & Strange Eng. coilovers for a set of those.

i can vouch for his shockwaves by saying there the heat! i really thought the car would sway alot with the air bags opposed to coil overs but his car doesnt really want to move side to side. because of his car i'm actually considering putting shockwaves on my camaro the adjustability and ride of air bags and the stiffness of coilovers you just cant beat that.

70 chevelle. i could of probually of done it diffrently but not acived the look or the backspacing i really wanted. i guess you could call it "rolling the lip". it just has about a 2 inch lip that needs to get taken care of so i can lower the car without contacting the quarter panel. and yes i really do like the shockwaves. i had to modify the opening in the frame to make them fit but thier a real nice peice. i don't regret ditching the QA-1s at all.

I thought you were referring to a 70 Chevelle but since your handle is SlowNova,I had to ask. To run a 10" wide rear rim on a 68-72 Chevelle/El Camino will require a wheel with at least 5.5" backspacing. I installed 20x10 TT II's w/5.5" BS and 275/35/20 Michelins on the rear of my former 68 El Camino back in 1999. They fit fine w/o any clearance concerns. If needed,I could have used a wheel with 6" backspace. What size 22" tire are you using and how tall is it? A 68-72 GM A-Body can handle a tire of at least 31" diameter.

well i used a 5 in backspacing i belive. i'll have to look. now i have to trim a little bit of the lip out becouse of it. no big deal, it will look alot better im my opinion. its a 285/35/22. trust me thier is a 2in lip on these quarters and i would of had to trim/roll them no matter what. :cheers:

Hi Jon,

I was wondering what are the tires sizes and back spacing on the Chevelle form the over hauling show.

I am diging the Famosa FL's wouldn’t mind running the same combo on my 71 Chevelle. Do they make knock off's for them?

By the way the pics of Courtney Hansen rock!

Street Rods are '48 and down. Even if you could find a decent street-rod site. They'd think you're crazy for asking about a Chevelle.

You're in the right place.

I'm a rookie at this and I have seen pro-touring cars with 20x12 on the rears. My own GTO will have 18x8 up front and 20x10 in the back. It all still fits under the wheel wells. Remember you are up sizing your rim for less tire. It all works out in the end. R.P.
