ive seen many similar topics on different forums guess i should have paid more attention so i knew for now. im debating between using current "extra" money + tax returns for either a vacation or new tires/rims or just save it.

if i go tires/wheels i want them to be the same size front and rear so i can still rotate. not sure if i should get 17s or 18s, they are only going to have street tires if i get to the point i want a "track set" with slicks or w/e ill mount them on the OEM wheels probably. whats the widest i could run and not have to roll the fenders or cut or modify anything, i could just throw them on and not have any major rubbing issues. the style i want i could get 17x9.5, 18x9.5, or 18x10.5 (see link http://www.wheelreplicas.com/c5.htm ). and for those wheel sizes what are the biggest tire i could safely run on each?

First of all, the only performance reason to run 18's is if nothing smaller will clear your brakes. Beyond that, you are reducing performance to add some bling.

The biggest 17 that just fits is the 275/40-17. Typically they're used on 17x9 or 17x9.5. For race tires in this size, up to 17x11 may be used but will tend to get heavy and I'm not sure if any trimming would be required.

The current "size to have" for racing is 315/35-17 all around on 17x11. Most people use the 50mm offset wheels. This will require rolling the rear fender lips, trimming the outside of the rear bumpstop, and using a 1/4" spacer in the front. They actually fit better in the front than in the back. BTW, this is not a very good size for street use.

I'm with sgarnett.

In there, you'll also find a page of 17x12s CCWs w/ 335s on all corners.

Those 335's seem to fit pretty good. I like the slight rear fender flare, looks good.

That's Casey Quinn's street mod car. He's in SoCal with us Mike. Not only does it look good but its fast too ;-)

I know what your getting at. However, driving my Nitto 315's on the street has been an extreme pleasure! It will be very difficult to go back to 275's ! Crazy grip.

I never intended to have bling wheels. However, everywhere I go I get positive commments. I have also found out from several friends that the tire/rim combo is very intimidated to the "street racer" crowd.

I rank this modification on par with new shocks/bars and skip shift delete. The car should come stock with it!

One thing left out in this thread (I think) is that the inner fender needs some motivation towards the car's centerline.

I've got 50mm offset GS 17x11s in the back of my car, only work needed was a adj. panhard and bumpstop work. I never had to roll the lips of the fenders.

Louis had 18x11 Forgelines with 335s on them and I thought 345s at one time, it required a lot of work (BFH, rolling) but they did fit on the back.

I upgraded my PHR (to G2 DA) and ran 3/16" spacers, and still had to pound my inner fenders to get 275s to stop rubbing on 17x9 SS ten spokes.

YES...
He asked me to host some pics so he could show them
He's also known as CQ55 in the boards.

I would like to see him at a local event and check out his car. Does he ever go to the auto cross at the Fourm?

Does anyone happen to know the offset of those 17x12's?
what else did he have to modify other than the obvious flare of the rear fenders and typical 17x11" mods?
Shazaaam! those look good!

Hello Everybody, I finally got around to signing up and checking out this web sight, When I heard people like Jason form Unbalanced Engineering were on here I knew this was the place to be. If anybody has any questions regarding my set up like my UE PHR lower brackets, 335's. etc. let me know and I will do my best to answer any questions you may have. Casey

i don't want to jump up to 17x11 yet, at least not for a street setup, if i started hitting the track a lot then i'd get a seperate set of wheels/tires.

i need at least 17 inch rims for brake clearance. i already have an adjustable PHR so i can play with that if need be, i was just hoping for more then 275s. man 335s would be sweet i'd have to make an effort to loose grip with those

Casey do you always have a co-driver?
Have you had problems getting heat into the tires?
Obviously in CA you won't have as much trouble as me in MI, and IN, but I have found in cool weather (75 degrees or less) that the 315's just don't heat well.

Do you have those insulated "tire warmers" some people use?

What is the weight and offset of those wheels. Specifically in the rear. I was planning to have the rear flared to make more room for the 315's. This may as well be done to accomadate the 335's

sent you mail.Casey

I'd be interested in the details of those 17x12 335's as well. can you post the details to the forum?
What else did you have to do besides flare the fenders, trim the bumpstop, and 'persuade' the rear inner fender well?
