AST 5100 fitment issue with TE37 (18x9.5)
Just installed AST 5100 on my friends car and he's having clearance problems. He has 18x9.5 +38 TE37 with a 12.5mm spacer and 265/35 square. According to APEX wheel fitment guide an 18x9.5 +28 setup should work so I'm wondering why this isn't.
I've told him to swap to 255 tires up front and if it's still close, move up to a 15mm spacer. But I'm just wonder why it's not working when according to apex's site, it should.

38-12.5= ET 25.5 which is still off of ET23 (28-5) they recommend for aftermarket suspensions with 255 tires. Add the 5mm of extra tire of a 265 and your friend would need a minimum of 7.5mm extra worth of spacer for a 20mm total spacer. Not sure why but many coilovers have the perch right where the tire goes (instead of above as OEM) which limits wheel/tire width inwards. Another thing to try are narrower tires. OEM 265s are actually 245mm at the tread. BTW I have 265s up front on OEM susp. and on 18*9 M513 wheels. Camber wont help with strut clearance. The geometry of the strut to the wheel does not change with camber. Camber will only help with outer fender clearance.

I've thought about removing the helper spring. Might just do it next time I have the car apart.

Removing the helper spring will impact the space available for the tire which can flex and contact. The only solution is spacers or diff wheels.
