Dampers in tune with the shocks?
Huh?

FWIW my experience has been that shocks affect ride more than springs i.e., a really stiff set of shocks will rattle your teeth in spite of softer springs on a bumpy surface. Perhaps a more compliant shock will ride better in spite of stiff springs?

That was my experience, Bob. The really stiff torsion bars rode fine with the street tuned Sport Shocks. It was only when Bilstein valved the shocks even stiffer that the ride turned buckboard.

I just came back from my first track day (California Speedway) with the Moton CS with stiffer Eibach springs and helpers. The car was just freaking fantastic. I ran one from soft in the rain and then added stiffness in the dry. I also drove the 240 miles from Las Vegas to LA on the freeway and the ride was great. Over large bumps, it is more harsh, but there is absolutely no bump steer. No complaints.
I have only run 2 track days, so I have not fine tuned it yet as Robin has, but I should be dialed in after the 48 hours of Las Vegas event with input from Kent Moore of Premier Sportscar Service and Craig Stanton who helped develop this package for Moton for the GT3! Yes, the development work has already been done. I've got the result. Those of you who are coming to the event can try it and see what you think. I am not experienced enough to preach about this stuff to others, but all I know is that my car felt great. It was point and shoot and under the heavy breaking at CS, the platform was settled. NO Issues.

I have installed much higher spring rates with Motons, and the ride was smoother than the GT3 (and way better on the track). I personally have Moton CSs in my car with 800/1200 springs, and on 90% of the streets I have less jarring than the GT3.

I was with Craig Statton last week at WSIR and he confirmed that he did devolpment work on the Motons. In fact that is why I am thinking of getting them. Group buy anyone? I also hear good things about Kent Moore. You are lucky to have him in Vegas.

Does anyone have insight on the Titanium shocks that Meridian Automotive is marketing? They might just be for Ferrari 360s. Less unsprung weight I suppose.

viper Bob: A number of folks up here in the Pacific North Wet agree on the dampening. It seems that the majority of the GT3 owners are moving to Motons.
Robyn: I did not see you Saturday at Bremerton. If you get a chance stop by Barrier. Black CGT!!!

That sounds really interesting, tell me more, which shocks are they exactly, the 7 way ones or the simple ones? Are Moton better that Manthey or JRZ etc?

The 7 way. I am not sure about JRZ, but I believe that they were a spin off of Bilstein and Moton are a spin off of them. Can anyone chime in on cost and performance between the JRZ, Manthey and Moton?
