i have just used the 316 compact in our local hill climb. it is the same car as the 318ti but with a single cam 1800cc engine which i replaced with a 328i engine. it has a LSD and Z4 steering rack but thats about all thats been changed. The tyres are remoulds and don't give much grip and the suspension is soft but it is great fun to drive and cost very little. i have had much faster times than this in other cars but never had as much fun
