Hi! Is anyone running solid lower bushings in their 348’s? Im in process of replacing all bushes from mine and saw that those shock bushes are toast. I would not want to sacrifice ride quality, why i chose oe rubber bushes to arms. But, i could make bushes from delrin si i would want to know if i make lower shock bushings from delrin, is it going to awful? Thanks
If to maintain the (relative) comfort of the suspension, I would not go with hard lower shock bushes (Delrin is almost solid). Although you will still have, I guess, the standard upper shock bushes (the "hyperblocks"), you will probably have increased road noise and vibration. The quick short impact on the wheel (like from rough road surface or small "steps" or gaps on the road) is taken by the shock bushes only as there is no time for the shock absorber to respond - the shock absorber is practically rigid when exposed to sudden short duration impacts.
Yes, top bush is oe. You might be right, and it would be best to keep rubber on lower point too. By looking how those are gone, they take quite a beating. Delrin would take it but, just might be too harsh Sent from my iPhone using FerrariChat.com mobile app
Image Unavailable, Please Login I just turned bushing to one shock. I might aswell test these, but i think i will end up replacing these with rubber ones. Is there any advantages with solid ones?
Yes but on race cars - hard (not totally solid) bushes provide actually more advantage when installed on swing arms which gives more "razor sharp" handling. Hard bushes on shocks (race cars again) also contribute in the case of considerably higher spring rates in a lowered short travel suspension to prevent small bounces.
Is there any good aftermarket rubber alternative to stock bushes? It would be nice to keep stock car behavior but stock bushes are $$: 163038 x 8 - $55 each 161571 x 8 - $70 each 161573 x 4 - $70 each 161572 x 4 - $115 each
I just fitted superformance shock bushes all round on my car; along with a load of other suspension bits. Seem fine and reasonably priced. But I don't have anything to compare against, other than what came out! On a road car I'm not sure I would go solid, I have found hard powerflex type bushes too hard on other cars!
Which version do you have? Can you compare it with stock? I have info from Superformance that their rubber version is much softer than stock.
I just went with their standard ones. The ones I replaced were original so 25 years old and had seen better days. I suspect the new ones are very similar to the originals when they were new. Image Unavailable, Please Login Image Unavailable, Please Login
Ok someone said their replacements were softer so trying to find other opinions whether they agree or not. Thanks
