Hey guys well i can report after more than 15 battery packs car is running well. No diff leaks. Shocks are great .
Only thing ive noticed is the steering rack has slop in it seems due to the very small bearings being used.
No breaks and car is as a mate said ...a weapon lol. Love it. Ps springs for shocks are available at 3 racing just check new parts and you'll find them there been there for awhile now.
