Finally pulled the trigger on a set of Koni Yellows, cars gonna be lowered is it a good idea to use some shaft mounted bump stops? If so should I go with progressive or the linear? Any other brands available?
Looking on Koni’s website it appears they only offers one bump stop for 24mm shaft, front struts
70.34.95.000.0
ID = 22-24mm
Length = 55mm
Characteristic = Progressive Soft

And two options for a 14mm shaft, rear shocks
71.34.42.000.0
ID = 14mm
Length = 40mm
Characteristic = Progressive Hard

72.34.48.000.0
ID = 14mm
Length = 25mm
Characteristic = Linear Soft

Also, what are the neoprene disks used for?

 

Based on some advise from a member over at www.frrax.com I'm just going to replace the front and rear bump stops with new factory style rubber bump stops.
Dorman 31061
UMI 2056

 

Ground Control has a bunch of shaft mount bump stops if you still want to go that route.

But ya, stock rubber bump stops are fine for 99% of 3rd gens.
You may have to trim them down a little of you lower the car, but that's ez

I have a video installing rear bump stops. A small cut and you can use super cheap jeep rear bump stops.

I did the same thing with a set of rear bump stops from UMI part# 2056, it was a lot cheaper getting the UMI’s than factory replacements.

 

I'd also like to know this..

 

From Koni
Those are called “bump plates” and simply sit on the top end of the damper and give a surface for the bump rubber to impact into and divert any debris or air pressure spike away from the piston rod seal. It is so okay an additional layer of long term protection for the seal. You simply drop the white disk down over the piston rod so it sits on the end of the damper body as the very first step of installation.

 

ya, the UMI part# 2056 is a rubber version of jeep bump stops.
they work fine, One of the few UMI parts I didn't remove from my car
