Sounds like your shock/spring combination (suspension) is too firm. Do you have coilovers or aftermarket shocks and springs? Aftermarket suspension can be substantially harder than factory, leading to a bumpy ride on roads that are uneven. Also, what size rims are you running and what it the profile on your tyres. 18" rims with a 35/40 profile will make for a fairly hard ride as well. The factory rims are 16" which are quite abit softer.

First of all thanks for reply...

Tyers size is 215/40ZR18
and rim size is 18X8 5/114.3 45M

Recently I went to Bob jane for wheel alignment and i told them that car is bouncing...They checked and asked me whether I cut the springs to decrease the Height...

215/40/18s are going to be very harsh, suggest going to a 17 inch wheel with a higher profile (225/40 or 215/45 or higher)

You probably also have hard aftermarket springs. Have a look and see what color your springs are and what kind of shocks you have. May need to swap your springs.

KYB Excel G are the go:

Front L: 334154 Front R: 334155 Rears: 341140

Available from practically anyone that stocks suspension and are reasonably priced.

Make sure you dont have coil overs before you buy though as this is just the shocks and not springs/strut tops. As Daniel said,17" rims will make a big difference too.

Excel Gs are shocks.

I'd be getting a set of king springs if I were you.

Will try that...SO I am bit confused now...sud I change Tyres first then Shock absobers ?

OK, heres a summary:

- Changing the wheels/tyres will definitely help as the greater the rim size, the harsher the ride. 17's are the best balance between handling and comfort.

- Changing the springs will help IF the ones you have are aftermarket and stiff or have been cut. If the coils of the spring are black then then they are mos tlikely factory and there is no point changing them.

- Changing the shocks will help IF the ones you have are aftermarket and stiff or buggered. The Excel G shocks are a good balance between comfort and handling and the closest youll get to factory ride.

A normal strut setup has 3 components, the shock, the spring and the strut top. These can be replaced individually. IF you have coilovers however, all 3 bits are wrapped up in a single part and all 3 must be replaced.

Hope this helps

Yep +1 on what dstocks said.

Also, if you are looking for new springs, try and search for progressive springs. Makes the car way smoother for daily drive and long trips.
