Talk torsions and springs. Options

[gnomefabtech]

Hello all-

So, I'm finally able to turn my attention to the suspension on my car now that it's running.

The car was hacked for a v8 when I got it and I have instead done my Hayabusa engine swap. I'll have to make a separate thread on the adaptor setup, but it's mounted north south and uses the original 901 trans. Dynos at about 300whp with turbo. 2k lbs overall weight. Narrow body.

The PO added some crazy stiff rear springs on coilover sleeves and they need to go. Also the front is way too stiff. It's all 911 front suspension and brake parts.

Questions:

I'm thinking about 140# springs in the back, but how long a spring should I use. 14"? 12"? Helper springs?

In the front I think it might have like 21mm bars, and that's way too stiff. Are normal 19mm 911 bars soft enough for a street driven 914? Or are there thinner 911 compatible bars?

Thanks!

Do any of you know roughly what a type 4 weighs fully dressed? Might help me guess at my rear springs. Hayabusa weighs around 220# with turbo, pumps, oil tank, and stuff.

My flared 4 weighs 1950 (44% Front / 56% Rear), but i've done some things (IMG:style_emoticons/default/smile.gif)

Stock 2200-2450 depending on the year and options.


I wouldn't go over 140lb in the rear. I have that on my autocross car currently and am thinking about dropping even lower. Stock front torsion bars, 19mm Tarret sway bar set full soft.
