I had this problem with those tyres, high speed paradas are like jelly!!. That's the weak link IMO. You have more than likely spent £10000+ on you car and only spent £30 on tyres the most important part of a car.
Only reason I bought quaife ATB is my car was a daily driver. As for diffs cusco or I'm not sure if Mfactory do 1 for starlets But if your serious about using starlet as a race car then I would look in to rear suspension design aswell because let's face it toyota's design is poo lol Rear camber/toe adjustment is a must for race car
Yeh man it's very good only thing about the area is there's not much to do if your not on track lol that's why Michael Schumacher go-karting is the place to go only 40 min drive and 10x better than nurburgring go-karts. 2016 nurburgring trip anyone?
Most people crash because they drive beyond there limits remember its NOT a race track its a public road. I only did 2 dry laps best time was 10min 6sec with yellow flags in a slow as fuck diesel Mondeo (Starlets should do sub 9min easy) >https://www.youtube.com/watch?v=4iJZdbDnUnE
