Firstly id do a full maintenance check on all running gear..

Engine compression,full service dont go cheap.
Brakes maintenace on calipers discs and good pads not OEM anyway.
Gearbox check for whines etc and make sure all gears dont crunch or are stuborn to change up or down.
Bushings etc

Then you want..


a good tight 2way diff or WELDED diff is as good if not better just dangerous on the road when wet maybe.. a good thing to check is if you already have either and what ration your final drive (CWP) is easily checked.

A half or full cage which are very available round here from 130-250e

Id buy a 4-1 ex.mani a de-cat and have a cat spare incase and an under axle straight to back box and a HKS mushy filter for a cheap fix!

Make sure you have coilovers on the front and either coilovers or uprated shock and spring on rear - the later being the best.

a fixed bucket seat and a gripy wheel wuth a fly-off button

go with an upgraded rear ARB in the rear.

then id get my name down on the next drift day!

stay with 14" wheels or 13s stay 4AGE get seat time and have a blast
