+2 rear suspension bump stop length
Posted: Thu Sep 09, 2021 10:34 pm
Hi,
I am currently installing TTR shocks and narrow rear springs so need to replace the aeon rubber springs. Currently trying to figure out what length bump I should use.
The original aeon rubber are 80mm and I believe normally fit on a 20mm spacer (mine were missing), so total length of 100mm.
The bump stops I have bought are URO Parts 1J0 512 131C:

Which are for standard fit for the rear of various VAG cars. These are ~125mm long and the TTR shocks nut has a ~7mm nut/ledge on it. So a total length of ~132mm.
From what I read on here, earlier engagement of bump stops/second spring is probably a good thing and particularly in this case where the initial resistance of the bump stop is lower than the aeon rubber spring. So I thinking that fitting these bump stops at there current length is correct thing to do.
I would be interested to know:
1) how much of the strut rod is exposed at a normal ride height on the +2 (so I can see how much travel before the bump stop would engage)
2) General thoughts on length of bump stops described above
Thanks,
Mark
