Going without Reinforced (XL) Sidewalls on track?

I never buy road tyres which are not XL rated.  Once you get used to them, they are fine and the car's suspension remains remarkably comfortable for a sports car.  Primacies are terrible tyres which should not be on such a car.  Yes, I've read all the 'but you can learn better as a beginner on them' yada yada comments but they will catch you out and are downright dangerous in the wet.

You can still easily feel the difference between, say, Goodyear Vector 4Seasons and Michelin Pilot Sport 4 with the former having a softer ride.

Do Michelin Pilot Sport 4 XL have a much stiffer sidewall than primacies (which are not XL)?

[GT86 PP Brembo pad upgrade]

Hello,

I have an GT86 PP Brembo.
I am planning of buying DBA T3 4000 discs: DBA 4654S-10 front, DBA 42656S-10 rear.

What compounds would you recommend for fast street + mild track/autoX? It's very important for me that the dust is noncorrosive and work good(at least like OEM) in the winter. I don't care if there's much dust, as long as it is not corrosive. Also, mild squeak is not a problem.

I was thinking of DBA XP(Xtreme Performance), Carbotech 1521(Bobcats)/AX6/XP8, Ferodo DS2500, Dixcel Type Z, Cosworth StreetMaster, STI ST262964S020 (Sti upgrade for gt86/brz brembo pads). I want to change front + rear, with the same compound.

I think this is what many people here look for in a set of pads, so your answers would help many others.

Thank you in advance,
Andrei

[Need help with wheels]

Hello,

I am from Europe, so buying wheels here from US is very expensive. (250$(6UL/RPF1 17x9)+transport )+24%Taxes. About 330usd(260GBP)+transport. 19%VAT and 5%PostTax also applies to transport.

I am looking for some wheels made in Europe so that I can get a better price.

I would like 17x9/17x8.5 preferably under 18lbs/8.5kgs which would fit brembo&sachs performance package.

Thank you guys in advance!,
Andrei
