Finally after several tries and a few months of testing/prototyping it's finally ready!!! The rear torsion bars will be made of 4130 chromoly just like the rest of the products we've been making---they'll be solid stock 19mm alloy steel and based/nearly identical to the whiteline design which is the best we've seen. The bar will bolt directly to the outboard holes on the coil buckets offering maximum control of the twist beam. The torsion bar will install in about 10 minutes without having to remove the coils!! They'll be primed and powdercoated white for durability and of course have our logo centered.
In early stages we tested with the whiteline bar which is 18mm/spring steel and it just wasn't quite enough rate for what we were trying to accomplish---they're a great bar and improvement for sure, but we needed more control/rate and better balance. We created a 19mm alloy bar and spent a few sessions at the track with it and just felt we hit a homerun---the car settled down a bit more and I was able to rotate it in lift throttle applications just like we strive for in the racecars---with our setup the car was finally neutral on a 3/4 tank of fuel!! The additional size increase and material will effectively add about 8-10% more rate/roll stiffness over the other bar and get progressively stiffer as the car is pushed harder in the rear.
The bar will make huge improvements on daily drivers and when used with our suspension setup provide a nice neutral and predictable platform for the driver! I'm excited---the bars are in production now and should finished in a few weeks and then coated and ready for shipping. It's taken forever it seems, but it's got to be just right...The best part is we'll be able to come in right at the $155 shipped mark and for the first 10 units sold---$140 to your door here in the states! The pic show's the general design of the bar---it offers excellent ground clearance as well---works with both the stock/and modified suspension! Pm me for payment info and we'll get you handled/on the list!!
