You can only drop that much weight if you're dropping the stock power steering and stock disk brakes. With manual steering and aftermarket brakes the weight savings is only 20-30 lbs, and that's with the stock UCA's and LCA's. Swap in tubular UCA's and LCA's like I've got and the weight savings will be just about nil. Not only that, but the weight is higher on the car because of the coilovers. The torsion bar set up will have a lower CG. The torsion bar weight is also further back than the coilover weight, so, it might not help the weight distribution that much either.
And now there's the borgeson power steering box too, which is 15 lbs lighter than the factory version. Still heavier than a power rack, but it's not a ton of weight.
This info is regarding the Gerst coilover set up, but I can't imagine any of the others would be significantly different.
A couple notes, those numbers were not counting the power steering box. If one seriously wants to pt a car, more than likely they want to have power steering, therefore they should had the 56 plus or whatever it was back in to the stock set up and add 1.7 lbs to the GTS for a power rack. Or 40 for the borgeston bix you mentioned.
I think we're spinning wheels here. The bottom line is that there are more than one way to skin this cat and each must decide what they want in their car. There's gonna be pros and cons to each type of suspension, but a suspension that is tuned and matched to the car, driver, and most importantly the tires, is gonna determine the "best" for that given car
What works in one car or at one course or with one driver, probably isn't gonna work for another.
Then you get into serious PT cars or the street driven, occasionally raced cars.
For me, I wanted full adjustment. I wanted improved KPI, improved weight balance as I like to neutral balance a car as a starting point for race weekend, I also like to play with spring changes, much easier to do that on a coil over car than a TBar (and cheaper, granted there is the inital cost but being that a good, performance rebuild plus upgrades is gonna set you back almost 2600 to 3 grand, it's a mute point), these and a few other reasons are why I went coil overs.
