I've ordered my Progress RSB for my Type S. What is the preferred/common or best setting (street or track). I don't track mine but want it to handle better around turns and still give a compliant ride.

 

track

 

Firm

 

For those that have it on "firm", have you tried it on "soft" and then switched? If so, was it noticeable?

 

i was on track then switched to stock and it was barely noticable just a tad softer on those damn NYC roads

 

Track/firm

 

I think I read something about the stock mounting points breaking off after a while when on the track setting. Can someone confirm this?

 

There have been a couple of cases (2, maybe 3?). From what I remember they all had upgraded Energy Suspension poly bushings and *I think* in one or two cases had the Comptech bar, not Progress.

The ES bushings used don't actually fit the TL properly, they have to be tweaked to fit, and that may have also contributed to the problem.

 

the oem endlinks are probably the weak points. if your car is slammed and you drive like a maniac, they might break.

I have 1.25" drop with coilovers on a medium setting. No problem with my RSB or endlinks for about a year now.

just dont push your components beyond their tolerance points and you'll be fine.

 

I have a 2006 TL manual and am lowering in the spring, should I wait for the Prog RSB until then? Or would it be good on the OEM suspension?

 

It's good anytime, as soon as possible. In fact, if I were to only have one single mod on our car, the Progress RSB would be it. You already have an oem RSB, the progress is simply thicker and stiffer. $120 bucks, 45 mins to install or remove. It improves cornering 3 fold. Its a no brainer.

 

But in those couple of cases I mentioned, it wasn't the end links that failed. It was the bushing mounting bracket on the sub-frame (1st two links below).

Interesting. Those threads also had several references to the endlinks breaking as well though. Also, I wonder if those are a result of using components not quite designed for each other. i.e. comptech rsb with ES bushings and therefor excessive stress placed on components. But again, without knowing their full setup and driving conditions, its hard to say. i.e. if they have slammed vehicles with tight suspensions, if they drive aggresively, if they have lots of bad roads, etc. Regardless, these definitely appear to be exceptions.

 

Let's move every general question out of the general forum Mod! What gives!

 

No. It's let's move every question about suspension into the suspension forum.

Anywho....keep it on track 24/7.

 

It's not hard cornering that breaks the mounts and end links. Bumps and taking driveways at an angle puts much, much more stress on these components than taking a corner at the limit.

Stock suspension cars will see a higher failure rate of swaybar mounting points. Stiffer springs/shocks take some of the stress off of the bar.

 

Stiff/Firm.

 

Some of you guys are funny. Why not just put steel pipe in place of the springs and eliminate the suspension altogether.

 

I guess I'm putting mine on track then....

 

Tried it.

Handled GREAT!! Like a slot car. ON RAILS.

Wife didn't like the ride though.

 

I should market a product like that. A steel pipe in place of the springs and shocks that will fit in the stock cradles that lowers the car by 12". That would sell like crazy on here.

Maybe a 75mm swaybar too.

 

Then we'd just call it Corvette suspension.
