I am not sure if you are talking about installing the USS at the same time as the rear sway. The areas of work are different for both items . If you do one first and then the other the only real work you are duplicating is the actual lifting of the car. Our items stop at the mount for the shifter while the extra stiffining for the cabrio begins further back. I hope this clears things up for you.

According to the following thread, it only took 20 minutes more for the cabrio: https://www.northamericanmotoring.co...ad.php?t=71397

The sway bar is by far the best bang for the $$ mod out there for an MC/MCS. As for an MCC, I have read where the USS provides better stiffness to the body resulting in reduction in body shake (cowl shake?) that is typical of most convertible cars out there.

Ranzo.....love the sig! Must be a racing simulator fan!

" 4 left, and 6 right over crest into big jump into long tightens the three caution rocks outside. Straight 100 onto tarmac. Hairpin left. 50 to finish, 30 to stop. "

 

Just a bone stock 2003 MCS with nothing added other than a few audio bits. I have done no suspension mods at all.
But looking to in the near future!

 

So i *think* you should have the SS as standard Equipment on the S, rear 16mm Sway bar.

So it goes back to the question of what you do with the car and what do you want IT to do ?
The SC Pulley is cheaper than a Bar but you need *friends* that have done it before - or pay to have it installed ( more $$$ than a bar )
USS with stiffen the car overall.

I know, I know the money is burning a hole in you pocket
But you should decide do you want to go faster or handle better on the Auto X or Track ? .
