What do you mean by squat properties? My technical english...
Gearbox thing, get Getrag 240 tranny from Manta B 1.8 OHC, bolts on to OHC and newer DOHC and Ecotec engine and if iīve understand correctly to V6 engines also. Thatīs more durable than thos R25/8 boxes and shifst far more better.
I have also built this Manta few years back, stil have it. Thatīs street car (alltough drifted little bit with at some point at comp level, mainly thatwise the rollcage). Itīs with Opel 3.6 12V engine from Irmcsher Senator and Getrag 265 gearbox from Monza. 307hp/418nm.
