Rear IRS Suspension Question

[fastbacker]

Im looking to build my 69 bug into a street car that doubles as an autoX car. I currently have a rebuilt 901 Porsche tranny with a lsd and a 200hp type IV 2.4 liter (yet to be installed). I'm going to run stock sized front fenders and 3" flared rear fenders (custom offset wheels with 275's).

I'm currently weighing rear suspension options. Having never built up a bug, I need some advice. From my research, I'm thinking of running a kafer 5 bar type brace custom made by welding in tubes - would tie into a roll cage. Also thinking of using 944 (or 944 turbo) arms and brakes.

Couple of questions:

1. What are the pros and cons of 944 vs 944 turbo arms and brakes on this set up with 3" flared fenders and 275's?

2. Any reason to stay with the stock irs arms?

3. Any better suggestions for the rear suspension?


Thanks a bunch-
