New Konis, What Else to Replace?

kentgbr · 03-10-2014, 06:17 PM

Looking to improve the suspension for better handling and occasional track use (2X annually). I don't want to impact the ride too much or lower the car. If Koni Yellows are used with the stock ZSP springs, is there anything else that should be replaced at the same time?

TIA

I liked Konis with zsp springs. Consider replacing the oem rear upper shock mounts with something firmer and your other shock mounts depending on your mileage.

Check your front control arms as well for leakage.

Consider an M3 front sway bar; it's a pretty good upgrade for reducing body roll/flatter cornering without affecting ride quality.

I'll be installing Koni yellows with sport springs and have 37k any recommendations on specific part brands?

I would suggest: M3 control arm set (front/rear) allows more camber play.
Thicker anti sway bars

Are you on OEM tires? Run flats? I'd change those, too.

I'm using Continental Extreme Contact DW's. They ride well but seem to have some sidewall flex under hard turns.

The car feels loose and has too much body roll for my liking.

shock mount suggestion is good since the labor shouldn't be much additional to changing the strut / shocks (hardly any).

similarly, camber plates, if that's a direction you might consider (Dinan has fixed plates on sale this month as well).

Was going to suggest bumpstops but looks like you got that under control.

As for the Op, you have a 2008 car. I don't know how many miles are on the car and perhaps I missed it skimming through the thread, but make sure to check most of your bushings (can't really 'check' the subframe bushings). If you could afford to do the M3 rear subframes I would suggest it.

I have E90 325i with ZSP and want to replace shocks with Koni yellow (springs will be from stock sport package). Do I need new oem msport bumpstops, or M3 E46\E85 bumpstops?

Stream · 03-14-2014, 03:13 AM

Bump?
