Hey guys I have a question.... As this is really interesting and I am thinking of saving up to possibly get these soon... BUT.

Do you or does anyone have any pictures of a stock body supra running
18 x 10 Front, 17 x 11.5 Rear - Titanium
Sets Wheels CCWH 1810-17115 93 Supra Set-Ttanium

How far does it stick out? Pictures would be extremely helpfull!!
Any rubbing issues? Do you have to roll the fenders etc...

What tire size would be reccomended for rims of this size?

Thanks for the help!!

Yes, you WILL have to roll the fenders. I use 285/30YR18 tires on front, and 315/35YR17 tires on the rear.

What advantage, if any, is there to running a 17" wheel in the back and an 18" wheel in the front, besides looking bad?

Just curious.

Selection of tires... For a long time you could only find decent drag radials and sizes for 17 inch wheels.

Then why wouldn't you want a matching 17" wheel/tire for the front?

The main issue is that no one makes a 285/35/17 tire, so people use a 285 on an 18" wheel instead (285/30/18).

Odd... I would think the proper thing to do would be to run a 17X10/17X11 set running a P275/40 and P315/35 tire set. You would get plenty of contact patch, and a proper matching front/rear aspect ratio.

Always worked for the Vettes...

would 17's clear a big brake kit? thats an advantage i could see, because quite a few people are running the 17 inch rear/18 inch front for road racing applications... just a hunch.

Main reason is that with an 18 inch front wheel you can run a big brake kit. That is what CCW told me.

This question gets asked often enough it should be a FAQ.

Top 5 Reasons for Running 18" in front and 17" in rear.

5. Big Brakes go on the front
4. 17" wheels in rear give a little more sidewall - so a bit more traction off the line.
3. Why not 18 in back? As recently as 2001, no one made a 315 series 18" tire.
2. Why not 17 in front? As quoted by PowerMac - no 275 or 285/35R17 tires.
1. And the #1 reason - these are the widest wheel/tire combination you can fit on the stock bodied supra - John Purner @ CCW spec'd these sizes to be run on Rhys Millen's Supra at the Pikes Peak Hill Climb. Numerous other track supras have run the same setup - e.g. OneLap Supra, etc. It works. Trust us.

How's that? I guess with 305/315 and I think even 325 tires available now in 18" sizes, you can probably run 18"s in the rear, but note potential traction problems for the cars with big singles.


Cheers,

PS: Why not 275/40R17 in front? (like w/ the vettes?)
2*(0.4*275 (sidewall height)) + 17"*25.4 = 651.8mm rolling diameter.
2*(0.3*285 (sidewall height)) + 18"*25.4 = 628.2mm rolling diameter. (about 1/2" smaller - which fits better under the supras front fenders.

285-30-18s are shorter overall than 275-40-17s, which gives you more suspension travel before the front tire rubs the fender liner. You have to run very stiff springs and/or longer bumpstops to prevent 275s from rubbing through the plastic fender liner into a wiring harness that runs above the front tires.

To answer the original question, they don't stick out, but you'll have to roll the rear fenders and possibly "massage" the sheet metal on the inside a little to run 315s, which is the proper size tire. They really fill out the wheel wells nicely. I was forced to buy Josh's wheels for street use :) because my car looked so much better when it was setup with the CCWs for track use.

I don't have the titanium finish (I wish I did), but you can see how far they stick out pretty well in this picture: http://home.comcast.net/~etyppo/HT4U4354web.jpg

315/35/17 for the rear

Wow, that could be my future racing wheels when I get a turbo. The color of the CCWheel is my choice, instead black center and polished center.
