I had always been a big member of the FWD is more fun the Haldex AWD club.
Now ive driven plenty of K04 FWD cars that are very heavily modified with practically every chassis and engine mod and IMO it is no more fun than the Golf R that APR loaned me. Both are excellent to drive, both corner like they are on rails but their is one massive difference.
Even a very heavily modified FWD struggles with traction despite good tyres, and a great chasis setup even with an LSD and semi slick tyres to try and tame the power. The Golf R however has absolutely no traction issues at all despite being on average road tyres.
All the Golf had was the Race Haldex kit in 'road' mode and the AST coilovers. Everything else was stock. The speed and grip you could get around an empty roundabout is immense, and thats not even the best bit. Theres the exit speed because your on full power soooo much earlier.
I agree the FWD might seem more nimble and probably quicker in the dry, but at Stage 2+ levels of power its to much for the wheels unless you use really sticky tyres and are pretty gentle with the throttle and then of course if theres a hint of dampness or its cold....well IMO its no contest, a haldex powered car is faster in the twisties. Power is no god if it just spins away.
