I am looking into getting a set of 18"X10" SSR GT3's. I was wondering what offset I would need to run to make these fit in front. I know a +41 will fit in the rear, but will this offset also work infront. I am not sure of what other offsets are offered in this wheel. I plan on running either 275/35/18's or 265/35/18's all around. Just for reference I still have the factory R1 suspension. Let me know what you guess think. The reason I want to run 10's all around is ease of rotation.

 

It won't work. The only way you can run 18x10 all around is with a +50 to +52 offset, which will require custom wheels (CCW, Kinesis, etc). You may run into a few "standard" wheels, like the Volk GT-7, that are 18x10 with a +50 offset, but that wheel won't allow bigger front brakes, which makes it kind of pointless.

There is absolutely no need to run 18x10 all around for street driving. Another very good alternative would be to run 18x9.5 +50 offset SSR Competitions (from the Tire Rack) at all four corners with 265/35 tires. This is a proven fitment.

 

I have 18x10 on all four corners for track use only. Offset is critical for proper fit. I do have coilovers but may not be absolutely necessary. The 18x10 is actually better than a 17x10 for coilover clearance. I did not need aftermarket trailing arms and also do not have rolled fenders. Only issue with clearance is that at close to full lock, you'll rub the fender liner in the front. This is not an issue for the track.

The weight of my 18x10 CCW's with Hoosier R3S03's in 285/30/18 is identical to the weight of my 17x9.5 Fikse Mach V's with Yoko AVS Intermediates in 255/40/17. This is probably mostly due to the fact that the Hoosiers are very light.

Aesthetically speaking, I think that the 18x10 looks a bit too wide for the front. From a functional perspective, they work fine.

 

What "rynberg" said, plus to fit the 18x10s, you'll need coilovers, aftermarket trailing arms, and have your fenders rolled.

Keep in mind too that wheels that big with tires are going to be noticeably heavier than stock.

 

As an example of what you should do and need to accommodate 18x10's on all 4 corners.

I do have the option of going with 18X8.5's in front with a +38mm offset. These shouldn't be a problem with fitment. I would still run the 10's in back with some 275/35's, but would probably go with 265/35's up front.

 

^You might rub with those 265/35s. I would go smaller, 255/35, even 245/35, however, with the latter size, there isn't much of a tire selection. What are your suspension mods?

 

The widest tire you should run on an 18x8.5 wheel is 245/35. If you are going to give up rotating the tires, I would go with a 9" wide front wheel (+45 offset) with 255/35 tire.

You should strongly consider my suggestion of running 18x9.5 +50 offset all around with 265/35. SSR makes the Competition, the GT2, and the GT7 in that size, at fairly reasonable prices. They are light, high quality wheels.
