If you change your stock springs to after market ones do the bump stops get changed too?

Most aftermarket springs use the stock bump stops. Only a few, if any, comes with bump stops.

Eibach Prokit for 07-08 TL-S does come with a pair of rear bump stops.

I think you might be referring to "spring isolators."


Bump stops are ALWAYS needed. Good quality springs will come with a recommendation as far as cutting the oem bump stops. But you would not typically need to install different bump stops.

I did mean bump stops. I spoke with Eibach tech support a while back and he specifically mentioned that the 07-08 TLS Prokit comes with new rear bumpstops.

If you have this set in stock and can verify, that would be awesome.

I ask this question in reference to the TSB regarding premature rear tire wear. I got my car with 14,000 miles and immediately dropped it and put on some wheels, so I never took it to the dealer to have the TSB done. According to all the posts the only work done for the tsb is replacing the rear bump stops and an alignment.

So if my springs DID come with new bump stops, all I need to do is take my car to a better alignment shop. Correct?

Im taking it in for service on the 7th, I'll ask them about the TSB anyway..... although I am afraid the aftermarket springs and wheels will not validate them doing the work for me.

We've had a lot of customers through here who have lowered MANY different ways. In the end, it does not matter how you lower the car, you'll need an accurate alignment to prevent tire wear.


The bump stop issue with acura, if I am not incorrect, is caused because the car had too much travel in the rear so excessive loads or movement of the sus was causing drastic toe angles under full compression. The solution was to limit the travel to prevent the toe wear.

When lowering the car you are resetting the neutral ride height and also limiting the travel. So the bump stop issue really has no bearing on the fact that you are lowering the car.

If the springs come with bump stops...great. If not, I probably would not worry too much about it. Rule of thumb: follow the instructions that come with your parts. Personal rule of thumb: if I need to cut a bump stop, I usually cut it about half as much as the spring is supposed to lower the car.
