My rear stock shocks are leaking and are almost dead (have only 120 000km). I have stock suspension on my 98SE and I'd like to ask what are the options for aftermarket shocks provided I'm not changing springs.

 

Same options as everyone else.

If you dont want an adjustable shock, go for KYB GR-2s.

 

You have many options, you will have to look around to see what kind of durability, adjustability, etc. that you want in a shock. There are many questions that you have ask yourself for a shock.

Check out the for sale or group deal forum for some quick options.
