Nice !!! Good job.
Mk1 chassis was better on grip surfaces (mk1 & 2 chassis are different so cant use mk2 unless you get different motor plate, L brace and top deck) so before you spend spend spend think about what surface youll be running on (if you are). If you are and on carpet (easier to keep clean) then diffs, slipper clutch, layshaft a zxr mk1 top deck and shock towers as well. I personally prefer the ZX steering plate as I get zero bumpsteer but if you want you can go for the ZXR MK1 and 2 version fibrelyte have this on their site.
