I bought the car like this, it is a converted R32 rack from what i know, apart from 3-point turns i dont notice it anymore, not much heavier than a datsun 1600 with f**kEN AWESOME FEEL/FEEDBACK. once i got past the discomfort from 3 scaphoid fractures i love/d it(still hurts every now and then but its getting better) pretty sure primal garage who can be contacted through "Xris" on www.nissansilvia.com did the work.
I will hopefully be at DECA in August and will let you know how it goes on a mini track then, but apparently it is fine to slide it like this
