Before I get told to search as there are many topics on this, I did. A ton. That said, I could not find a definitive answer on spacer size for the rear Carerra S wheels (C2S) on Pilot sport 4s tires size 305. I have the SPASM suspension and want a good flush look, but not to stick out at all. I see that many are running 7mm in the front and 15mm in the rear with 295’s and appears to be the perfect set up. That said, with 305 rears, I’m thinking that I should just go 8mm in the front and 8mm in the back. Possibly 10mm in the back at most? Can anybody help chime in on this? Thanks in advance for the help. Looking at ECS spacers.

 

most people do 7mm/15mm for flush fitment on .1
.2 only needs maybe 5-7mm in the front but nothing in rear

 

You need 15mm front, 5-7mm rear for 245 front and 305 rear

 

I have 7mm in the front and rear but I have PZeros on my '19 GTS. The rears are perfect and the fronts could use a few more mms to be perfect but I like they way they look; pics are in a thread about spacers in this forum.

 

Fronts look good, but don’t they rub?

 

What’s the rear offset on your rims Bob?

 

Beats me! Here is the thread I posted pics in and they are the OEM Carrera S 20s: https://rennlist.com/forums/991/1142...for-gts-2.html

 

By the way, Suncoast has spacers on sale now, which is where I got one of the pairs I am using (other pair bought from here in the Marketplace).

 

No spacers PS4 305's on 997.1 GT3 rims

 

 

Can you post a side shot, one that shows the Red lettering on the tires?

 

Looks good. What’s the spacer sizes?

 

I don't know how that got deleted... 15mm Front 18mm Rear. 295 Michelin PS4S. in hindsight I should have got the 305's as the sidewall is shaped differently. The 295's have an angular area to protect your rims on your wheels whereas the 305's are a boxier shape.

 

I don't have the letters on the back because I caught a nail and replaced the whole axel; even though I had <1K miles on them. I got them from https://shop.tiregraficx.com.
