Hi JRV,

Hi JRV,

I posted this elsewhere but got no reply. Do you know the answer to these? I do lots of engine stuff but bvasically stock suspensions have always been bullet proof for me. So since I'm modifiying for racing here are some ??
Question on lowering front suspension of 348. I have not got to the rear yet. Here is the situation. You can loosen the lock ring but when you turn the adjusting nut the spring winds up and everything springs back on release or wrench tension. This happens because the lower spacer rubber is really old and it is basically welded to the spring and adjusting nut and second because the spring is still in tension squeezing the rubber spacer onto the adjusting nut. So What I need to do is compress the spring to relieve tension so I can turn the adjusting nut. There is basically no clearance for spring compressors I have seen. Does anyone know what spring compressor fits the 348? I hate to have to make spring compressors...I am pretty lazy.

Second question if the upper and lower spacers are really full rubber then the ultimate ride height is dependant upon these spacers being good. Mine look like beat up bushing rubber so if these are bad does anyone know of a better spacer I can use i.e. less compliant?

Third, If I go to the trouble of replacing the rubber spacers I may as well replace all the rubber bushings in the A-arms. Does anyone know who has decent bushings?

Billy,

it is possible with

Billy,

it is possible with very liberal amounts of silicone spray to turn the lower perch (once the silicone has saturated in) while holding the spring and get them to turn without rebounding.

the other method uses silicone spray and some cheap spring compressors (with the hooks ground away for easy slip fit) slipped on and tightened to relieve some of the pressure.

the rubber insulators are there to dampen vibration, prevent squeks and rattles on street cars, most race car setups don't use rubber because of it's propensity to give false adjustments and change thickness when loaded.

the substance most often used to replace the rubber, if neccesary is nylon or hardened urethane.

What else?
