I'm currently restoring the rear suspension on my 75 1.8l and wanted to get other's suggestions regarding rear bushings.
My shafts are fine and I'm planning on re-using them. I already have a set of bushings. Mine are the "Daystar" polygraphite set that you can get from multiple vendors. These are in AutoAtlanta packaging. These puppies fit stupid loose in the arms... I worry about squeaking... I don't like straight poly bushings for the most part. Would you use them? What grease would you use on them? Normal silicon grease for urethane bushings? 914Rubber has a rubber set that are reasonable. $ 44 PMB and Elephant racing have rubber sets that are far more costly. $92, $240 This car will be a mildly upgraded streetcar for enjoyment not competition. I'm leaning toward the 914Rubber set... What says the hive mind? |

QUOTE(yeahmag @ Aug 27 2023, 11:52 PM)  I've used a bunch of different rear bearing/bushing combos in the past: plastic, delrin, roller, all sucked. These are the best I've used and wholeheartedly endorse them. https://www.rsrproducts.com/product-page/re...ear-bushing-set QUOTE(Geezer914 @ Aug 28 2023, 06:35 AM) Rubber bushings are fine for a street car to maintain stock performance. I went with the RSR thermoplastic inserts and never looked back. QUOTE(Superhawk996 @ Aug 28 2023, 08:08 AM) Ever stop and wonder why 99.99% of automotive OEMs including the likes of McLaren, Porsche, Ferrari, Lamborghini use rubber bushings? Hint: it’s not for cost reasons. Those RSR bushings are interesting! I hadn't seen those before. A shaft in a tube. Thanks for the link! SuperHawk, I've been doing this a long time, yes I am fully aware why everyone uses rubber. Even with rubber many manufactures "tone" down their suspensions over time because the non-enthusiast owners demand it. The BMW M3 is a perfect example of this. AN E30 M3 (all rubber) is too much harshness for almost anyone and if you change anything it will beat you to death on the street. I have an E36 M3 These got toned down a bit to make them more user friendly and are the sweet spot in my book. Put yellow billys on it and it's harsh, any urethane and it's harsh. BMW heard their customers and the E46 M3 got toned down a BUNCH. This car benefits from suspension improvements as it was set up soft enough to be far more comfortable for thier average driver. All of those cars started life with rubber... This 914 will be my father's final "sports car" and will be set up more for comfort. He's an 83 year old multiple myeloma survivor and ALL additional padding has been removed frm his body. When he was healthy he weighed 180, now he weighs 130. This is the main reason I'm not going Elephant poly bronze or (now!) RSR shaft in tube on this car... |
