just converted my escos to rwd
best thing i ever did ,love how the 2wd drive train goes and handles ,yes its harder too controll in general but ,lots more fun ,,
yes it can bite you but so can a 4x4 just not as easy too lose....m last saff was 500bhp and now escos 330 bhp will be 500 soon .......rwd also easier on gearboxes,diffs etc etc
i personally hate the ford cosworth 4x4 gear change ,you have to wait a week before changing gear ,2wd just smash it in
totally transformed my car ,obviously i am biased to rwd ,once you have a big power 2wd cosworth nothing is as good imo
anyway its up to you, just my view on the matter
