The left front shock recently blew on my 130K 2000 TL. I had both sides replaced with KYB GR-2. Would it not make sense to also replace the rears in order to restore the ride quality? Thanks.

 

is it not riding the same?
if so, yes. replace the rear two as well.

 

you might as well.. 130k

you're gonna have to replace the rears sooner or later.

 

The KYB's are a bit softer in the front than the original shocks in compression damping so the car has less understeer and a more neutral balance. The rears are about the same as stock.
I found the best ride/handling out of Tokico Blues.
Either way at this point you should replace all 4.

 

has enough miles to merit them --
test by bouncing the corner of the car
compare front and rear --bounce 3 times and release,,how long to stop?

 

Thank you all. Will replace the rears. Do the springs require compressing to install?

 

If they are factory springs then yes.
