Hi, is the offset to low for a track car?

I run Rota Grids 15 x 7 with +20 offset and I seem to get along okay, but the car is very much dual use. Feels a little flatter vs the factory wheels (which I use when dailying it) with the wider track and possibly a touch 'tramliny' although that really only comes out on the road.

I'm not slammed, about 110 at the front and 114 at the rear running Tein Flex Z coilovers.

It's not strictly speaking legal - the top of the tyre is inside the arch but if you plumbbob it the bottom third is a little beyond the guard. I've only had it rub a couple of times, once on a big dip on the road when I had the front coilovers set fairly soft, and the other time exiting Karussel at Lakeside.

The starting point for picking wheels for track cars is to look at the regs for the competition and class that you want to compete in. While 15x8 +20 should fit your car (probably with a bit of guard rolling) it's not permitted in quite a few competition classes.
