I keep reading different reviews, looking for input. C street ND2 with progress bar, looking for more rotation (coming from a V8 XA class car, so I'm used to big rotation). Recently got a set of Koni Sports and want to set them up with the best setup to help rotation. This car is driven to work on nice days so maintaining some decent ride quality would be nice if possible.
I've seen using the following setups all around and wanted to get input
Brians testing
Front: unknown ?? (possibly gwr soft)
Rear: Two 58mm GWR hard bumpstops, top nub shaved off to stock length
Front: gwr Soft
Rear: Medium + sliver of Hard bumpstop
2022 Nats CS winner
Front: stock cut down ½"
Rear: Penske Blue
from the gwr website:
front: medium
rear: Hard (is one bump stop tall enough each side or do you need to purchase 4?)
CS Koni Bump stop Recommendation
Re: CS Koni Bump stop Recommendation
No wrong answer here, I have had at least dozen different rear combos that worked, my ND thread here same page shows what is on the car currently. Front OEM stops cut in half and I used the smaller half.

Re: CS Koni Bump stop Recommendation
I did a ton of searching around on your builds and that was what I came up with. Makes sense for the front!
In the rear did you like the 58mm hard bump stops the best? You said the rotation was pretty intense at first. That combo required FOUR bump stops, right? Two cut down on each side to stock length.
Do you remember how it rode with that setup?

Re: CS Koni Bump stop Recommendation
We are starting on alternative material for rear, currently my favorite was this one. That is two of our hards back to back and shaved down a hair shorter than stock rear ND2 stops. I have been through numerous variations on this idea and nothing has been better. Takes a bit of training as the driver to get accustomed to it because this will bring the rear around rather suddenly when you hit it. But if you can smoothly get into that second cone of 5 cone or longer slalom then the car will sit on this and you can keep adding gas and exit the slalom 10mph or better speed than you started it.

Re: CS Koni Bump stop Recommendation
Are you gluing these together for the rear? And what would you do with the Penske blues?
Double bump stops rest on the shock body and keep the metal hat piece by itself at the top of the shock?

Re: CS Koni Bump stop Recommendation
Ah, surprise - looks like a friction fit, at least to start.
Re: CS Koni Bump stop Recommendation
Yep, no glue, friction fit and they don't do anything anyway until squished from both sides.
