If the track is really rough use bilstiens(personaly i dont like them dont let the car set) I use afco would use carrera/QA-1's or even pro's are ok. What ever you pick get the take apart shocks though.

we have run bilstiens for 6 years and have had very good luck. have learned so much about shocks by just trying things and can't complain about them at all. But as always just looking for some more speed and was things about the importance of letting the car do the work and not he shocks helping do this. Bilstiens always pushing out has to have an effect on rebound of springs and that tends to bother me alittle.

The new Bilstien SN series, with the floater pistons and Nitrogen gas pressure would be a whole new ball game for you.

These shocks are trick and highly tunable, with valvings etc, plus you can tune with the gas pressure. You might look into them if you wanna stick with Bilstien brand, and learn more about the internal workings of shocks.

There are a single tube design, much more effiecent than a twin tube desgin. Plus you can digressivly valve them like normal Bilstiens. Then there is the Nitrogen gas pressure, adds a whole new realm. Basicly just like a LM shock but steel.

I wish i went this route, but we went with QA1's before i knew these were out. We still might switch due to the single tube design and the nitrogen pressure adjustments.

The best improvements i found so far with QA1's is the shock fluid, which is much to be desired from the factory. Other than that there a straight fwd shock thats easy to change the valving wich is nice.

I like bilstiens personally. Are these new bilstiens IMCA legal?

IMCA won't let you run the Scrader valve to gas up the Nitrogen.

I always forget YMCA rules, i run UMP. So i guess they wouldnt be legal then.

Following IMCA rules, i would run QA1's.

Krom,
The Sn's are worth the money especially if you want to experiment/learn about shock behavior. We went to them at the beginning of the season on the l/m and I have learned so much and have come up with a lot of new ideas to try just using my homemade shock dyno. If you do switch to a rebuildable I would recommend starting a relationship with someone with a dyno, its pretty easy to get out to lunch if you don't check your changes on a dyno.

IMO monotubes are the only way to go for any track conditions and once you adjust your setups for them you won't want to go back to twin tubes.

This is probably a stupid question but what is the diffence in makeup between a monotube and twin tube? Which style are the normal $109 bilsteins that most people run?

The biggest advantage is consistancy. A twin tube will build/retain heat more than a monotube. A twin tube is essentially a tube within a tube, the inner tube houses the piston assembly the outer tube acts as a oil resivoir. A monotube is also more easily rebuildable/revalvable.
All bisteins are monotubes.

Not that I'm advocating the breaking of IMCA rules, but you can get an inverted shrader value to put on the Bilsteins. You can contact the shock rebuilders to get them. It's not as easily detectable as the standard valves. Depends on the level of your tech. Again, not telling anyone to cheat, but information is always good.

Kromulous ,
What are you using for oil , have you tried anything besides the qa1 oil? I am not real happy with mine thus far.

Chad,You wouldn't by chance be stretching the rules a bit by running these "inverted schrader valve shocks on your car would you?
I would be shocked if you were!(pun intended).

Red line Fork oil.

Call: Naake Suspension Specialists
(916) 771-0109

They should be able to hook you up with an oil upgrade for the QA1 shocks.

DMAN- absolutely not! By the way, anyone interested could also give Mike Naake a call at the number Kromulous listed. He definitley knows shocks and stays on the cutting edge.
