I am going to order some 19" wheels for track use on my .2 GT3, Most likely going with Forgelines. Will 9.5" front and 12.5" rear fit under the GT3? or I should stick with 9" & 12'?
Also what is the difference between the GA1R and new GS1R?

My plan is to run 265 front an 325 rear tires. Maybe try 295/345 down the road.

Thanks.

I've got an extra, brand new set of 265/325 Trofeo-R tires for sale. These are easily the best 19" track tires available that can be driven. Almost as fast as a Hoosier, but very driveable daily. I use them on all my cars.

Let me know.

I have a set of the GS1R's. The only differance is more materal is removed from the lug area.

You can go 9.5" up front if you plan to run fairly aggressive camber with the R7's, but I would recommend sticking to a 12" wide rear (especially with the 265/325 combo).

The GS1R's have a bit more lightening detail, more evident on 5 lug wheels, however there is still a few subtle weight saving variations between it and the original GA1R. Mainly the chamfered outer lip on the GS1R.

Shooting you over a PM as well!

Do the GT3 an RS share same wheels offset values when using 19x9.5 & 19x12 wheels?
