Conversion to Coil-over Help

[RonRyon]

I am converting my ’73 standard beetle chassis to coil-overs, front and back. I have narrowed the front beam 1¼” on each side with 2½” dropped spindles and disk brakes. Also, I have removed the torsion leafs. I am looking for stock length coil-over shocks with 6” of travel. I believe the spring rate should be in the 125 to 140 lbs/in range,

With regards to the rear, I’m using narrowed trailing arms (1½”), Eagle Products’ coil-over conversion kit and disk brakes. I plan to lower the rear by 2½” and will accordingly use shorter than stock shocks. Based on my calculations I believe I will need 275 to 300 lbs/in springs.

Does anyone have any experience with a similar setup or have advice/recommendations regarding brand of shocks and spring rates? Any comments will be greatly appreciated

I'm in the process of converting mine also. But I have a '74 Super. I have the rears. I went with a rear 400 lb. ;8" spring; 1.9" dia. I am also removing my torsion bars. I was told by the company to get 375 lb. rears. I got 400's. The fronts (I have a super) I will be getting 10"; 275 lb. (approx 100 lb. more than stock 1303); 2.5" spring. I told the company everything about the car and what its purpose will be. I was told it will have a streetable ride and will be still aggressive enough for track use. This company builds custom coilovers for all types of race and street cars. Prices VERY reasonable and US based. You will probably need a smaller diameter front as you have a standard, and 125-140 seems a little soft since you did remove the torsion leaves. To figure out the length, you need to measure between the mounts when the car is compressed. Also I don't know what you use your car for, but mine will be street with occasional track time. If you want more info PM or e-mail me.
