Make sure you find a T-18 rear diff that has swaybar mounts! (early modles came with no swaybar or mounts, later did) or have facilities/abilities/shanilities to weld some on!

I run the JDM Vented (but not slotted/drilled - even more to be gained!) brakes with Decent pads, fluid, and maintanence and you'd be surprised what cars they can keep up with remember she only weights around a tonne!
