Car Bumpy Due To Turbo Kit Added

[gnatoyota]

Hi guys,
I recently added a turbo kit from TurboSpecialties (turbospecialties-race.com) to my 9th gen corolla. The weight of the kit seems to dip the front height abit and now the car is very bumpy when going over uneven road...

Anyone has similar experience of adding weight to the front and such uncomfort happens? How do I overcome and get back my comfort?

Change absorber? Change spring??

Thanks for any solution or advice!

Pretty hard to believe the weight from the turbo and associated hardware (even looking at the more weighty cast log, heavy intercooler, sectioned tube from stainless instead of aluminum, etc.) - hard to see more than 70-80lbs of weight.

Need some more details - what turbocharger did you get, how did they run the piping, etc.?
What mileage do you have on the car?
What other mods are you running?
Stock suspension or aftermarket - if aftermarket, what springs/struts are you running?

If that much caused the ride to degrade, you likely had blown struts to begin with. If the car's static ride height dropped a noticeable amount - that points at severely weakened springs (springs control ride height, struts control ride damping).

Measure the ride height front and rear, left and right. The ride height in each corner should not be grossly offset - if they are, could be something completely separate from the springs/struts causing you problems - like something got disconnected during the build, like they took off center cross brace to pull the oil pan to drill/weld in a oil return bung - if they didn't tighten the center brace correctly, suspension could be moving excessively, causing the poor ride.
