I ask, because stock the car is on 40s, not 35s. The 35s are usually the size on the 19 stock wheels.

right but the stock 40s arent 275mm wide. and 40 percent of 245 is different than 40 percent of 275.

Bringing this thread back from the dead. So has anyone been successful at 18x10 et 25 with 275 tires and kw cs? Ive been told mixed things.

I currently run 265 on 10 squared and they seem fine. Those two guys who run the ring like crazy also ride on kwcs and 265 michelin cup tires so if it works for them it should work for me.

Any input would be great. Thanks!

I'm running et18 on 18x10 with 275/35/18 Michelin PSS. I'm about 2mm from hitting the KW spring. Et25 absolutely does not work. You will need a 5mm spacer and even that could rub the spring slightly.

Slicer with your 18 offset i guess i can run a 10mm spacer and have a little more wiggle room.

With such an offset do you have to run -3 camber?

Im currently set at -2.5 / 0 toe for both street and track driveability. Thinking of getting 275 with the 10mm spacers and extended bolts/lug conversion. Thanks in advance.

I'm at -2.0 degrees camber in the front with zero rubbing. 275/35/18 Michelin PSS, 18 x 10 et18 wheels. My ride height is 25" from the ground to the fender bottom - measured at the center of the wheel.

Thanks. When i went to realign the car the car was too low and when i took of the wheel i wore the purple spring perch down to the metal on the wheel side?! Yikes.

I since raised the height so that there would be no rubbing at all and is fine now. Ive decided its too much of a headache to deal with either spacers/extended nuts/removal of helper spring and will stick to 265. My buddy who owns a shop tells me to stop being a pussy and run the fatter tire

The perch was raised with my 18" track tires on. If it clears these, will putting on my daily zcp wheels affect anything? (Maybe the bigger wheel still rubs against perch?) i read in a different thread (a comment from one of the apex guys) that running a bigger wheel will alleviate the problem more as the wheel will move away from the perch even more. Havingg a tough time picturing this in my head. My thinking is that if i raised the perch to clear the 18s, running a bigger wheel will move the wheel closer to the perch. Will call my alignment shop tomorrow and ask. Thanks again. These freaking kw cs are amazing but a headache when it comes to the ideal square setup!!
