No no.. not for my Airtrek. My Airtrek has enough ground clearance eventho I am using Eibach Pro-Kit. I am referring to my RX8. Okay, I know I sud put under the Rotarian Forum but there aren't much response from them. This question is more of general actually.

Anyone has experience with bump stopper? I mean they are rubber rings installed between coil spring's spiral. This is to avoid the spring compress too much, causing undercarraige bottoming.

My RX8 is Mazdaspeed version, so it comes with lowered suspension. When driving alone or with my wife, it is fine. But with my teen kids on board, I scratch the undercarraige whenever I go over speed bumps around my housing estate. This is really annoying.

Installing bump stopper is the cheapest solution I can think of. My next solution is to sell the Mazdaspeed suspension and get adjustables which I am very reluctant to do so.

Those rubber spacers you put between springs will eventually deform the shape of your spring since some parts of your spring compresses and the others doesn't.

It's a cheap solution but also a gradual way to kill the spring.

I've got very high tolerence on comfort and harshness level. This is after I started using Airtrek Turbo where stock coils are already very hard. Coupe that I am using Eibach Pro-Kit now, it's worse! So my family got used to it. In fact, we feel that RX8 is 'softer' than my Airtrek, hahaha..

Thanks for your reply bro peeche! :)

if like that maybe you can try the bump stopper first. if ineffective you can upgrade to adjustable later. by selling back your mazdaspeed coils will raise some funds.

You should try use a slightly longer rubber bushing/stopper (the one which is inserted to the shaft of the shocks/dampers).
I agree not to use those rubbers which are inserted in between the coil springs because it will also change your spring rate.

No need 5 figure la.... nowdays taiwan brand also got reputable air suspention , but the pump n tank is huge, take 1/3 of your trunk.

Best u can go is swap the suspention or spring with other stock which is higher spring n still keep the comfort ride...

I got some feedback from the Rotorians... I guess I'll bear with it. :) It's a sports can and meant to be low anyway. So I need to change myself to adapt to it.
