Hi there
I have 1200 gx that i use for gymkhana but i need to get my front suspention harder , can i use any other datsun coils spings and stabiliser bar as there is to much body roll and the front end is too high

help please

Curious as to what class you run: When we first started running the 72 Coupe, I ran in stock class and the car was very competitive at local autocross (our Version of Gymkhana). Never found the car to have a lot of roll.

240Z springs will fit on the 1200 strut perches but will likely raise the nose unless you cut a coil out (legal in South africa?) I seem to recall the 120Y front bar can be made to fit.

If your in a mod class then lowering the car should be easy enough and getting a set of sway bars would be the way to go. sizes we use are 7/8 front and 5/8 rear which I think is around 21mm and 15mm roughly.

the easy way out is put a motor in it

We have very small rear wheel drive classes,1 for under 2000cc and 1for over 2000cc,front wheel drives are huge thouth

I have a alfa romeo limted slip diff in the back that made the back end come down a bit now it stands with the front end higher than the back,that can be the cause
I can cut springs as my car is not road legal

click on my web link ,maybe that can give an idea

will 120y d coil springs be harder than std 1200 gx ones

1200 GX uses the same springs as regular 1200: 89.6 lb/in

B210 (120Y) springs are slightly heavier, but not by much. They are longer though. B310 front springs are 90.7 lb/in for A12 engine.

Most racers look for somewhere around 175 to 225 pounds is what I've heard.

you may want more damping
not just more spring
