I saw a set of 18s on the for sale section with tires here and need to get the fitment on my fc down. I know I need spacers for both the front and rear, but I also need advice on the front rubber.

Nominal Width, Overall Width, Offset
Front: 8.0”, 8.5”, 40.0mm, 235/40-18
Rear: 9.0”, 9.5”, 45.0mm, 265/35-18

The rims are Mille Miglia, MM11-3, weight low 20's lbs
The tires are P Zero Corsa System tires with about 50% life left.

Can I get the 235/40 tires in there with just spacers? Stock fenders here, RB springs and KYB AGX struts.

 

I do know that you need spacers and also need to roll your fenders or buy wide body fenders at corksport.com

 

for the front, youll need at least a 7mm spacer, if not 10, if it will fit under the fender.

for the rear, 15mm should do.

 

i personaly run a 215 35 18 on my 88 n/a w out any spacers and i have no probs whith them

 

not sure about the spacers but your fenders should not be an issue. i have 18's with 255/35 tires on. back fenders are stock and unrolled with no problems. I do have after market front fenders but i dont think 235s should be a problem.
