My Caterham is a track day car only (not registered).
I'm very pleased with my ccurrect Quaife qbe15z, 5 speed, h pattern, alloy main case and cover.
My Duratec does not rev very high as the max power is at 7.300 (engine built by Ammo).
To adapt my max speed I'm using 2 different rear tyres depending on the track .
With Michelin 22/54/13 max speed is 217 km/h at rev limiter (ok for A majority of tracks like Spa, Magny-Cours...). it´s way too short for Dijon or Hockenheim.
With Michelin 24/57/13 max speed is 230 km/h (like in Dijon, but slower in Spa or equal in the best condition as the straight line is going up).
Acceleration is fine with both tyres.
I don't have the torque value in my head, I need to check when back home (I'm currently on holiday).
(Max speed values are coming from AIM data login using the AIM GPS antenna).
