zl1 road course setup

[@ReaperZL1]

has anyone ran a 295 front and 325 rear on their 5th gen zl1?
I'm curious to know if it will fit with 19" wheels.
also what tire does everyone use for a dedicated track tires (never gonna see a road)

I really like the Goodyear Supercar 3 used on the Gen6. I have the standard tires but they have stood up to lots of heat cycles. GY also have an R compound version for the newer ZL1 1LE which has the 19" wheels similar to the Gen5 z28.

do you know how wide they are off the top of your head, id like to run a 325 in the rear and a 295 in the front.

I like Nitto NT01's

305/30-19 I believe is the OEM size for the ZL1 1LE
325/30-19 is also available

Tirerack shows the available sizes (click on the Sizes tab)

I haven't tried these yet but I will. I really liked the Goodyear F1 Supercar G:2 that came on the 1LE for it's intended purpose, so I imagine I'll like the 3R even more.

I know 305/30-19 fits easily, I've got the Bridgestone RE71R in that size front and rear. Front fitment really depends on wheel offset.

305/30-19 is shorter than stock so it can lower the car a bit, and final drive will be shorter if using that size in the rear.

Others have run the same sizes, and some have 325 in the rear I think. Rear fitment is easier than the front due to suspension clearance in the front - worse case you need spacers, but then you get more poke.

For me I'd prefer to run square setup for handling balance.

do you know your wheel offset and width to be able to run the 305/30-19 up front? I'm assuming 11 wide.

I haven't run a square setup before but it already handles like a dream with my 295/315 combo I'm running. I am however on bmr lowering springs if that will effect fitment at all.

just trying to get all the info I can before I order wheels to get the right spec.

Yes, 19x11. My current track wheels are Forgestar CF-5, ET27 in front. They will not clear most suspension without spacers, which makes for poke - not ideal.
They do not fit without spacers with my Ridetech HQ coilovers - which have a pretty normal 2.5" internal diameter spring set up. Also depends on where the spring perch is at relative to the wheel.

I haven't test fit yet with my MCS suspension set up, but I think it will fit without spacers since they are using 2.0" ID springs in this case. I was looking for the widest setup, with the least poke. Not sure I found it, but I'm marching on with it.

I run 315 X18's square for SCCA T2 with MCS and Hoosier A's.
