Viper ACR suspension tuning advice

[Toronto_ACR]

Can someone please help me. I have a 2000 ACR and I wanted to know how I would go about tuning the suspension. I understand that I can lower the car another inch if I wanted to. can someone tell me if this is true. I dont see anything in the owners manual about the ACR suspension.

In the 2000 model year they had two different types of shocks. Do you have Konis or Dynamics? Also, the absolute maximum you should lower the car is 3/4".

The lower spring perches can be unscrewed a few turns to lower the car. You can't do this with the tires bearing weight. Most of us who have experimented with lowering agree that about 3/4" (19mm) is as far as you should really go. Measure this from a frame hardpoint near the tires, not bodywork. Lowering changes something called "bump steer curves" and corner weights. If not checked & readjusted, they can lead to squirrely handling. The average alignment shop will probably be capable of checking bump steer, but not necessarily competent. Corner weights are checked with scales. Seek out serious racers.

The shocks are also externally double-adjustable for compression and rebound. This affects comfort and handling. Keep good notes and be methodical.

Stay in touch with Paul Mumford, as he is the "King " of ACR setups. Trust him and Dean, as 3/4th an inch drop is the maximum to go, regardless of the type shocks.

Dynamic's have an external oil resovoir; Koni's do not!

Does anyone know where I can get a manual for these adjustments. I want to learn everything I can about it.

Thanks

Your car should've come with a supplemental ACR manual. Also, I think the Dynamic shocks have a "Dynamic Suspension" sticker on them.

Jumping onto this older thread I'd like to know if a 2000 ACR suspension can be put onto a 2000 R/T10?

Is it just the springs and shocks, or more components?

Toronto ACR tuning and lowering your suspension will not help you I plan to spank you and send you home to MAMA CRYING.

Nevermind. They were sold.
