Can some one help me with this becouse im planning to upgrade the 35 year old suspension in my 245 i have the ipd 25,22 swaybars and now looking for shocks and springs the look and feel i want is a little lower and stiffer and still dailyable i think i have the overload springs on the rear and ive heard they are good when cut the options i know of are
Bc racing, "cheap" but the rear sucks and i have to weld the fronts
​​​​​​Kaplhenke, 2000€ and i dont know what specs i would want (also i have to save for a while to get that
And the endless amount of shock and spring combos that there are konis bilsteins etc
So can someone with experience help

 

Having the IPD sway bars is a good start. Those will probably give you the most bang for the buck. When it comes to shocks and springs it really depends on your goals. There's really four choices for springs 1) retain stock springs (and add a better shock) to retain stock ride height 2) progressive rate lowering springs (such as Eibach's) 3) fixed rate lowering springs (H&Rs), 4) coil overs where the spring and shock are a single unit with an adjustment ring that lets to select the ride height. The important thing is to select shocks that match.

If you go with a stock spring you can use Boge (OEM), Bilsteins (they have the B4 "touring" and the B6 "heavy duty" ) and Koni as the top names. Each is a little different. Koni's offer the most flexibility since you can adjust both the damping and rebound. Bilstein B6s are firmer than stock so a simple upgrade would be to keep factory springs and use the Bilstein B6s. Some people have noted the B6s actually raises the ride height, but I didn't see that on my 850T.

If you go with a lowering spring, then you need to use a shock designed for the shorter spring travel. Bilstein B8s are just that, and I'd guess you could match a Koni to a HR or Eibach spring. The thing about progressive vs fixed rate is progress springs have a soft end and firm middle so as to give a compliant ride most of the time and then stiffens as wheel travel increases. Its a nice compromise for daily driving but if you want to do some weekend sport driving, you may opt for fixed rate springs. Coil overs are the best of breed since the spring/shocks are already matched and the better brands give you lots of options for adjusting.

Final thoughts - 1) dont forget about your wheels. lighter wheels will help keep the tires glued so if you go with a plus 1 or 2 (ie 16 inch+) shop for the lightest rims you can find. 2) lowering springs will change suspension geometry. Do research on whether its recommended to install camber plates etc for the new ride height.
