do not get a bigger turbo. You'll be 10 times slower Pat.
its all about seat time. The more time in the seat, at the track will = quicker lap times.
Id suggest getting sway bars and a wheel alignment. The KU36's are still a good tyre. Not a true semi slick however much better than street tyres.
Once you have done some more track time and had some driver trainers in the car, you'll shit in a 1.13 anyday of the week
