Is this really necessary ?

[Matt49]

a25rjr, were you able to identify how deep into the bump you were? I think that's the key thing on the xmas tree stuff and I would imagine it was integral to your success with it. To grt74's point: homework! But RE does a great job of providing the data so back to my point of not needing a spring smasher.

[a25rjr]

Honestly, no. With our car on the scales, we tried a couple of different springs and bump stops and ended up with this combination. Jerry at Shy helped us tune our Ohlins to it, and it was even better.

Its amazing what you can learn with ratchet straps and your car on scales! lol

For sure :-)
And amazing how one can benefit from a good relationship with a good shock builder. I've been preaching this for a while.

Opinions seem to vary wildly on the subject of how hard it is or isn't to get a bump setup working

No doubt, Matt! I hope Jerry can keep up with the relationships he made at Shy. He'll def put Afco back on the map with their shock program.

its just alot of work,and every driver is different,some want more drive and the ones that like to stay on the gas like less drive(momentum type drivers),i know this I've never had any of the guys i have helped run the exact same thing,shocks are a very big factor in these setups,thats why i build my own stuff to an extent(ill get the curves i want from my builder,because i don't want to spend three days trying to find it, but i may change my shim stack for more or less control)the biggest problem that most people don't understand with double adjustable shocks is that there is only a 150lbs to 200lbs worth of adjustment,sometimes thats just not enough,
these setups will require good notes,your not going to win with these setups right out of the box unless you test it and get it where you want it
some of the national guys have 5-10 rf shocks or more and there all adjustable,if that tells you anything

if you do not have access to data acquisition, spring smashers etc,etc, a go pro camera works well, and they are relatively inexpensive. I play with one watching the RF to get it to do what I want, when I want. I watch the pull bar (I run a modified) and watch the lr and lf suspension. you can learn a great deal watching that stuff.
once you get a visual on where the suspension is moving to in travel, you can somewhat get the same attitude on the scales and get a good idea what the numbers are and start playing with LR droop, spring combos, bar settings weight placement. you cannot get it exact on the scales to track comparisons, but some data is netter than none

jerry has practically unlimited resources now that hes at afco , he has helped me tremendously, but you have to be able to explain to him exactly what you want or need to do. With out proper info from the driver, no one can work magic......

Why is that car attitude faster? That's the question you need to answer OP.

[a25rjr]

More: aerodynamic, increased downforce
: loaded left rear, increased forward bite
: more roll steer, allowing car to turn better when on the gas

aero,it will almost create a suction effect on the car,you want to keep as much air as you can from getting under the car,and then use the air thats hits the car(think of all the money we spend on going faster when air is free if you understand how to use it)
