Thunder Hill has two nice long straights - you can generally top 120-140 with a decently powerful car.

What you need to knock down a quick lap there is brakes most of all. I had some monster Brembo GT's that allowed my little WRX to haul down from the triple digits and dive into the turns (paired with Tein coilovers). If you go up there you'll see how you have to cut in really fast towards the apex and then do a fairly ragged kick out the end to gain speed into the next straight.

Infineon is just a nightmare of walls imho :)

Yeah, looking forward to Thunderhill in my BRZ. Infineon is fine in a supercapable car like an R8 but something with less grip is probably scary. (I got all wheels off in the R8 anyway)

Also depends on your car. If you are looking for a straightaway for outright speed, Big Willow lets some cars get up to about 160 or so.

In this case, an R8. Infineon doesn't have much in terms of straightaways.

Not a fan of Infineon personally. Turn 1 scares the heck out of me =)

1 is the big uphill thing? 6 is the scary one (down the hill)

V8 or V10?

V8
