You can make a zed great fun to drive with some money
My car is raw as hell as handles like its on rails. It does bite if you don't treat it with respect. The acceleration is very aggressive and the ride is quite stiff.
I know for a fact that I can throw my car round be roads very quickly as anybody that's been on a run will testify.
Even on a small track like Knockhill the Lotus's, clios sports & s2000's have issues on the twisties trying against me in my car without running nos. The combination of roll cage, kw's, arbs, arms and my wheel allignment makes my car awesome to drive. There's minimal body flex and roll and the car is very responsive.
I will however say that getting the zed to this point is very expensive and time consuming and if you had to do the same on the s2000 there's no doubt it would be even better than the zed. However it is possible to make the zed a very capable car.
