That track looks like a lot of fun! Hmm, to bad it's a four hour drive away from me. Running at Spa-Franchorchamps is top priority for me this year. But I need a set of semislicks as there are some high speed corners which indeed eat tyres, like you noticed at Zandvoork. I was thinking about a 235/18 square setup.

How did you like the JB4 btw? I found the power to be too much on/off and brutal on the racetrack, which made me switch back to the Procede which is way more linear.

If you want a cheap and very effective suspension mod, I recommend the M3 front wishbones and control arms. They add a bit of camber (much needed at the track) and tighten up steering response. It's really one of the best mods for our cars!
