Suspension Set-up Question

[Snowman]

A quick question for all the Motorsport experts in here.

I tested my car yesterday for the first time with the new MCA shocks and for the most part they were fantastic.

In high speed applications they were perfect and big bumps they absorb without notice and mid-corner the car has way more grip than it has had before.

BUT - at lower speeds the car feels a bit bouncey and if there are bumps under heavy braking the car also bounces around pretty bad at the front.

I'm a bit new to the different types of rebound settings available in the MCA's so not sure if there is a specific one that this scinero might be effected by (high speed / slow speed) - or whether its a spring thing or an alignment thing (although the settings are the same as they used to be and I never had this issue with the old set-up)

Any feedback would be appreciated.

hey Snowy

i havent got a copy up here

but if you dont already have it, you could ring Murray and ask him to send you a copy of the setup instructions which has adjustment explanations.

cheers Russ

I have a copy but it's not helping me much.

I've had some people say its the "slow" adjustement since its at low speeds - but others tell me the slow adjustemnt is for slow piston movement such as in corners (where its awesome).

Others tell me its the fast adjustement since its over bumps - but its great over bumps anytime except under brakes.

So thats why I'm confused and don't want to stuff something up needlessly!

If it is just road undulations then it is low speed.

Mostly high speed is for when you are kerb hopping.

Its all relative to the piston speed in the shock. So if its a sharp sudden impact then its high speed, if its undulations in the road surface loading the car up and making the car light etc then its low speed...of course there is a window of cross over.

If the bumps under brakes are a problem then it sounds like its high speed rebound that may need some work

As Roy said Snowy, try decreasing the front rebound rates (ie, slow down the rate of rebound) and see if that makes a difference.
