Hi teeners. Getting close to exorcising the demon air bubbles from the brakes and I notice something in driving around. The inside rearview mirror is worthless! All I can see is the pavement 20 feet back.
So, I'm thinking the front is too high or the rear is too low. The car has Koni coil overs on the rear and unknown struts on the front. The Konis are adjustable but only for damping, and they're over 15 years old. The rear wheels have a significant amount of camber. I watched one of Ian's videos about installing rear coilovers and if I follow his rule of using a straightedge from the rocker panel the rear is too low. However, I believe I could also lower the front pretty easily. I'm new to the 914 world so all opinions and thoughts will be considered, absorbed, and used to bring the BB to the straight and level. Thanks. Oh, a photo is included. Attached image(s) |

According to the manual the ride height in the center of the rocker is supposed to be 140mm or 130mm car loaded. This is of course with stock 25" tires or 165 SR 15 on 5.5Jx15" rims.

According to the manual the ride height in the center of the rocker is supposed to be 140mm or 130mm car loaded. This is of course with stock 25" tires or 165 SR 15 on 5.5Jx15" rims. well done finding that in the factory manual. (IMG:style_emoticons/default/beerchug.gif) interesting - mine sits considerably higher than that - unloaded admittedly. its a level 195mm to the bottom of the rocker panels (330mm to top of rocker panel) above ground with about half a tank of gas. running proper stock size 165s. the back is sitting at the ht it was before we took all suspension apart - took a reference measurement. edit. - i see where you mean - in the glove box manual? the 130mm seems to be the lowest level of floor clearance which might be lower than sills. i went out and measured the car. my overall ht. agrees with glovebox manual at 1230mm. i also measure a clearance of 130mm to the u/s of the little rubber flaps that hang down in front of the engine bay for lower pressure area air flow. lowest hanging things on the car. perhaps that 130mm is a reference to ground clearance at the lowest point which is the flaps? interesting to learn mark henry has his car set up with i inch from the rim to rear guard. 25mm in metric. i have approx 95mm clearance from the rear rim to the rear guard (close to 4 inches) and i think we did a good job of setting it up stock, which was my aim. so anywhere in between is going to be good. i noticed - it might have been my imagination. that when we cranked the front down, the rear seemed to come up a tiny bit. most folks probably favour getting their cars lower. the car is still running original springs - softest factory spring. it drives great with a full load of two people, cases of wine, luggage, full tank of gas, on bumpy country roads. i run pretty skinny michelin XAS tyres so its more the vintage driving experience i am after, without the vw engineer induced plough understeer. easy enough to play around with rear springs and go from there to get what you want. you don't want the nose up. |
