So I was looking to get new custom wheel set up. I was looking at Work wheels vs-xx 18x8 but I'm trying to figure the off set I would need. I was thinking of getting +35 but I want a good fitment between tire and fender without rubbing. I'm running cx racing coils max lowness, going to run a 215/40/18 tire much help needed

Hi Carl!
I like to use this tool to estimate fitment.
Fender distance to hub is ~85mm

Good luck.

Yep. I had a set of C6 ZR1 reps to put on my last Sonic but they never got past the test fit before I sold the car. Now I want these C7 Z06 reps but they aren't making them in a 8.5" wide size yet.

Oh cool, mine weren't reps
I ran 3inch spacers to make them fit in the back. 245 fronts 285 rears on Goodyear eagle f1 2**** you auto correct!

Hi guys, new to the thread and new to the board. The first mod I'm looking at for my RS is the Eibach lowering springs. I like my stock 17's. What would be the perfect tire for the car with this lowering kit?

225/45/17?

I'd like to get a little more traction though than from a 205. After dropping the car, I'm planning on stabilizers front and rear to stiffen her up. She's plenty fast for me, I just really like to turn although I could always tune her in a year or two.

225/45 is a good size that's close to the factory tire diameter, but at that tire width you really need wider wheels to avoid sidewall flex. Almost 9" of tire width on a 6.5" wide wheel isn't good for tight handling. I'd look at some better handling tires in the stock size, like the Bridgestone Potenza S-04 for Summer tires or the Continental ExtremeContact DWS for all-seasons. The stock Hankooks are designed for a long-wearing smooth ride in all conditions at a low price rather than great handling.

Has anyone used these on a 17x6.5? Sonic Wheel Spacerby DDMWorks, 3/16"

I'm pretty sure someone has put these on after lowering and it made the wheels sit a little flush to the fender

Ok. I've read through this thread and still trying to wrap my head around it making calculations.
I'm buying a set of 18x8 wheels. Et 38.
I plugged in the numbers into the wheel offset calculator.
Looks like I will be .35" short of flush or roughly 8mm.
I will also be installing Eibachs at the same time.
Tire Rack recommends 215/40's, but I would like to run 225's if possible.
Will I have any rubbing issues with the drop?
Any recommendations on tire sizes?

does anyone else run a little bit of negative camber?

Andrew, I like the Continentals. Maybe I will try them in a 205/50/17.
