315/50/17 EtStreet R’s Installed

[DeadSpool]

Stepped it up from the 305’s to help first gear leaves, street hookups and less than ideal track prep. Quite a bit bigger than the 305’s as you can see in the pic. i won’t be able to test them out until I get the engine back in but they sure look like they belong there.

What size were the 305’s?

Pic on left has 3/8” spring spacer, right has no spacer. I think I’ll have enough clearance to run without a spacer but I guess we’ll see.

Definitely a big difference in size. Looking to upgrade from ss 305’s to r 315’s possibly. Please update your thoughts on them once the motor is back and you get some runs on them.

Any report back on these? Looking to order a set of the 315/50 R17s today

Yes, I ran them all last season and they were great! I had to use both a 3/8 inch spacer as well as a 1/4” spacer to make the outer sidewall not rub the inner fender lip under full squat.

This is with gt350 springs, I think they would be the same ride height as OEMGT Springs, but cannot confirm. Maybe someone else can?

what is your camber set to in the rear?I assume you had to weld the spacer together. currently using the 3/8" spacer w Steeda .5" drop drag spring but it rubs on squat. I was worried about the spring staying in place since less of the coil is making contact with the seat at the top.
sick car kinda looks like mine
