I'm in the process of installing new Koni Yellows, Eibach progressive springs (23-4041) from MSA, and the rubber suspension kit from Car Source on my 73 Z.  Since the car will hopefully be about 1 ½" lower, I'm thinking I should add some bump stops, and don't want the hard poly ones (going for an old folks ride 😉). MSA only sells the hard ones.   I've seen other threads of soft bump stop talk, but no specific part numbers used. I called about the FatCat ones, but they mostly offer Miata advice.  Heard others use the Koni stops, but which one?  Koni strut shaft is .856" (21.74 mm), so I'm thinking the Koni 70.34.95.00 one is the one used, right?  It's over 2" long, should I cut it down to about 1.5" ?  Anyway, just looking for some advice.

Thanks, Ken

For the soft foam urethane bumpstops the dia. of the hole doesn't matter much as you can push them over most if not all struts.  With these you won't feel the hard stop you get with poly urethane.

Awesome, thanks!  Needed the 🥾 too.  👍

All,

I am looking for a bump stop that matches the OEM as close to possible in size, rebound and appearance. (I have read that the aftermarket urethane is not as compliant as the original hard rubber.)

Has anyone identified an alternative to the NLA original bump stop?

Thanks,

Keith
