Not completely true, some KV6's have had some HG problems but they are less common than the K4 engines.nope not at all, no head gasket problems on a kv6
it has a great chassis, and the mk2 with a bit of tweeking can take 9x17" rims with some serious rubber.thats good because there are plenty ZS 180's around sub £1000.
. . . .but not everyone will 'modify' their bubble to the same extent as you have thoughI wont lie, modifying the bubble's (200/25/ZR) can be very expensive and turning them into capable track toys can end up costing a heap of money.
They are bloody good fun though!
By the time you update the brakes and when you consider that the 160 has a stronger gearbox with closer ratios and a lower final drive, then perhaps a 120 would not be so cost effective if you decide to go the ZR route.Another option has just appeared, a ZR120 for £650.. What about modding that from the ground up, which I was gonna do with a 160 any way,and then put a vvc in it.
