Default Just purchased a 04' STI, some newbie question about 'bumpy ride'

Is it me or are all STI have bumpy rides? I have couple passengers sitting in the rear and they complain about my ride being bumpy.

Also, are stock sti shocks pink in color? I noticed my STI has pink shocks, just want to know if it they were ever replaced...

Thanks!

That's a performance trade-off... that's present in order to match the power, otherwise it'll be harder to control.

For someone who wants a more comfortable ride, I'd suggest trading for a Legacy GT. Not as fast but can be made faster, and wow is it comfortable.

how many miles is on the car? struts may be worn.

but as for the comfort of an STi.... well you bought a performance car that is relatively inexpensive. Not saying that it was a nice chunk of change but you didn't buy a porsche.

It is an STI, it is a sports car, with firm suspension, it is not meant to have a soft ride.

You could try letting a little air out of the tires.

Driving faster may also help - rally-type suspensions can be very rough at low speeds, but often smooth out at high speed.

Bumpy or do you mean they bounce? Are you talking about the head bobble you do when you go down the road. If so you need firmer springs. Prodrive or Pinks come mind. Go pinks if you want a bit of drop.

aaaaahhhhhhh!!!!!!!

Performance cars are not supposed to have a crappy ride. Porsche's in particular ride amazingly well considering how stiff the suspension is. There is a HUGE difference between a firm suspension where you feel bumps in the road, and an '04 STi, that bounces in response to bumps.

STi's "bounce" - especially the '04's (and the strut bodies are more of a red than pink - if your struts are pink - and I'm talking Mary Kay Cadillac pink - then they're probably the aftermarket adjustable STi struts) partly because of the spring/shock/strut top combo, and partly from the seats, believe it or not. Search for "STi bouncy seat" and you should find a thread about modifying the stock seats to reduce the bounce. Modifying the seats (or switching to '02-'03 WRX seats) will significantly reduce the bounce. Going to a harder strut mount (also called a "top hat" or "strut top") such as the Group N mounts or some form of solid camber plate, will help too, as will going to a stiffer spring such as the JDM Pink spring or Prodrive STi spring.

Modifying or changing the seats along with slightly stiffer springs and strut tops will get you to the firm-but-not-bouncing-down-the-highway ride you are probably looking for. Ignore the people who told you that you should have bought a Legacy GT. Unfortunately, it means spending about $1K on a car you just spent a bunch of money to buy

i meant amazed at how smooth the ride is. do a search on JDM STi pink springs and look for reviews...they are overwhelmingly positive.

ignore the people who think the car is supposed to have a crappy ride because it's a performance car. the car bounces because the inverted struts have high stiction and present a nearly infinite damping rate to the spring with small movements, forcing the undamped springs (the tires and strut tops) to move, hence the bobble.

the stock STi springs aren't radically stiffer than the wrx springs considering the extra sprung weight. the real culprit here is that the inverted struts aren't suited very well to street cruising, in my opinion.

what can you do to improve? koni inserts or kyb agx's to replace the inverted struts, or stiffer strut tops and jdm pink lowering springs should you want to keep the inverted struts. All season tires help a bit too, but more with impacts and less with the bounce.

good luck
