Top speeds in km/h from Spa on Kemmel straight braking into Les Combes:
BMW 120d (348hp): 250
Ford Focus (341hp): 241
Honda Civic (342hp): 244
Hyundai Genesis (340hp): 242
Nissan Skyline (330hp): 247
Peugeot RCZ (360hp): 254
Range Rover (350hp): 239
Renault Megane (355hp): 247
Conclusions: BMW and especially RCZ are scary fast in a straight line. I think that it would be good to bring all cars inside of 10km/h, especially since the RCZ is not the fastest through Eau Rouge and
still is the fastest by a mile at the end of the straight. The BMW with wr-stage 2 has a lot of potential now, but it's difficult to drive consistently fast. The Range Rover and the Focus might deserve a very mild boost. It's easier done for the Evoque, because it's using PL already. The Focus would require an additional part, which might boost it too much already. So, bearing in mind that Furi is in one (as far as I remember), don't overdo it!!!
