Have been occasionally tracking my 156, and recently fitted powerflex bushes for the front axle - upper and lower wishbones. First impressions were great, with noticeable stiffening of the car, with little worsening of the ride ( at least on FSDs and Eibachs combo).
Went to a track day where I used slick tires - after the TD, when refitting street tires, noted that the front lower wishbone bushes on the right side and the rear lower wishbone bushes on the left side had slipped, moved out of its housing. ( photo)
At he mechanic, we could see that the front lower wishbone bush iron sleeve ( the metal tube provided by powerflex, that stays in the inner part of the bushing) have been ripped open ( photos) and there was significant damage on the rear bushes.
Also, one of the bushes that was still intact showed signs that it was slipping - note that the bush is offcenter!
Had no option but fit standard bushes and wishbones. I already habe my rear axle and upper wishbones powerflexed, with very good results... What you guys think? Did the bushes were incorrectly installed? Or the pressure of a track day on slicks was too much for the bushes?
Thanks for the help!
