Q1 How much of an affect does the rear support brace have on the overall rear stability by using alu instead of the std plastic.

Q2 There is not much information about the spring rate difference and their applicability onto various track conditions especially when it comes to clearing jumps is there a std to sort of adhere to deciding that this spring rate would be ideal for better jumping capabilities or are we pretty much basing things on bumpy or smooth tracks only.

Q3 If I was in need to gain further droop from the 808, I would relocate the suspension and droop screws accordingly, however is it also possible to gain more droop to angle shave the tips where the droop screws sit ??

Q4 What would be the maximum and minimum ride height ever possible to use on the 808 say Front 25MM and rear 26MM etc.

Q5 Once arms are bent minor bends from crashes etc can one use the arms after boiling them and leveling them out or just replace. I am not used to things not breaking it's either breakage or not, the previous bran I was running never bent they just snapped or wore down to excessive play the 808 just holds together much better, but need constant check up on the setup station to make sure setup readings are still there.

Hi Bren,

On Bump steer I noticed something that has me re-thinking the advantages and disadvantages of bump steer. In general I always read that the less bump steer the better. Some bump out can help to make the car more stable when braking. I think this holds true when all 4 wheels are on the ground. But how does bump steer help or hurt you during the moment one wheel touches the ground when running through rough sections or landing?

There is a certain chassis from another manufacturer that has tons of bump steer. This is a very competitive vehicle and I can't imagine it wasn't designed into the car. This car works very very well through rough stuff like moguls and washboards. This chassis also has a lot more droop. But I don't think it looks quite as good as the 808 when all 4 wheels are on the ground.

For a rough track setup, more droop obviously helps. But is there an advantage to running more bump steer (bump out) if you want to optimize your setup for the rough sections like moguls and washboards? My buddy and I are guessing it makes the car less twitchy but we would like to know the theory behind all of this.

Any suggestions on a starting setup optimized for moguls and washboards? We need to fly through these to stay competitive on our local track. We also have smooth sections with large jumps and the chassis works great in those areas, but I think we are getting killed though the rough sections.

Thanks in advance!
