Yes.
Here in EU I run Dunlop Direzza, which is even faster than A052

For those with vorshlag plates, how much camber did those get you? Wondering if I’ll need to order arms too. I’d like to have 3-4* range to play with.

I would give them a call. They answer the phone right away. I bought mine for a different issue with my Ohlins. But it turns out with my adjustable LCAs and the Vorshlag plates, the shop says I’ve got way more adjustability for him to work with.

You can run 997 gt3rs brake ducts, works great.

Inspiring! I’m looking forward to seeing how these Verus ones do.

Do you consider a heat cycle a track session? If so, then about 17-19.

I experience a noticeable difference in grip CRS vs AR1. AR1's like to slide around even when new. Either way I'll probably never use them again because they wear like stinky cheese and are miserable to/from the track.

32psi has been my sweet spot for most super 200's. I start at 26/25 cold.

You are right about the AR1's and pressure, they go up a ton from heat and they seem to hate high pressure.

I wish Maxxis made bigger sizes. I’m at their largest (275/35-18) and another set just arrived in time for Christmas It could be in my mind, but I feel like you can immediately go out on those Victra RC-1s, they‘re grippy as boogers from begging to cord, at various tire pressures. I really liked the Nankangs CRS but they were definitely more tire pressure sensitive, or I‘d slide more in turns I normally don’t. And even when I’d drop the pressure down, they still didn’t have the same grip.

But who knows if it’s the tires until I put the Victras back on with my new setup. I did have faster times. Looking forward seeing if I can maintain that or surpass it on the Maxxis tires.

Can I run 295/30 tire (thread width 298mm) on a r18x10.5 wheel with around -3.2 camber and ~10mm lower than stock in front with no spacers or it wont fit/will rub bad?

what offset? What suspension?

Ohlins R&T. Offset anything from +25 to +50 can be custom made. Was thinking 18x10.5 +25.

+25 would be pretty aggressive.

Last year I ran 295/30/18 Conti ECF's on 18x10.5 +35 all around with zero issues.

This year I ran 295/35/18 CRS V2 which are about 305mm wide on 18x10.5 +35 with zero clearance issues.

I mean I can specify wheels to be +30, just want them to fit/not rub, so isnt lower offset "safer" ?

Im on 18x11s with a 37 offset and no rubbing unless im at full turning lock. They are pretty close to rubbing the springs though. Dont think I would want to push the wheels out any further.

Well, is there any downside going lower offset? Why not push the wheels out bit more ?

Then you're stuck with that offset. If you go with a higher offset you can always run spacers.

Rubbing on fender lip/liner

I dont care, all i want for track wheel is to fit good, I wont change offset anyway.

Rubbing on fender lip/liner

Ah ok. So I should run as high offset as possible to clear brake caliper but not rub fender liner?

10.5" wheels arent hard to fit up front. 35 offset has been proven to fit many times so thats the route I would go. If you can get a 40 offset, then get 5mm spacers to go with them. 30 offset is just pushing it.

It's a balance between clearing the strut/spring and not contacting the outer fender.

Like @Evolution stated, +35 is a good known fitment with MK5 Supras on coilovers.

The 295/30/18 isn't a hard tire to fit honestly. Here is a 295/30/18 Conti ECF on 18x10.5 +35:
