anon_uk Posted November 3, 2019 Posted November 3, 2019 So my gen 1 is getting on a bit, I think some of the bushes at least need changing. And I am wondering if bushes need changing, should I go to polyurethane? Driving style: No track use, mainly fast road Are there any other options than PowerFlex? Thanks all

And I am wondering if bushes need changing, should I go to polyurethane? Driving style: No track use, mainly fast road Are there any other options than PowerFlex? Thanks all Can’t speak ref a Cayman: but I had quite a few Powerflex Yellow series bushes (Engine mounts x 3, gearbox mounts x 2: and a few front suspension components) on my previous car. ***No fit, longevity or quality issues at all. Which was only used on the road and after perhaps 500 miles of settling-in (Few vibrations at tick over at first) I felt (sic) they improved the car substantially. The solidity, feel, improvement in gear change etc was much improved and very noticeable - with little to no detriment imo. And I’d have no qualms using the (You soon get used to some increased firmness over stock) same again in a different car. Hope that helps in some way. Good luck......
anon_uk Posted November 9, 2019 Author Posted November 9, 2019 So, I placed my order from Design911 and its come through. However, they are all the black version, how much difference in stiffness is there?just thinking if its worth sending back, or work with what they sent. I don't think I did anything wrong, or ordered the wrong part numbers but I was expecting "ROAD USE" and not "TRACK USE" PFF57-501-23.5 STABILIZER BUSH BOXSTER FRONT 23.5 MM *PAIR PFF57-502 LOWER ARM CENTRE BUSH 986/996 Powerflex PFF57-503 LOWER ARM REAR BUSH 986/996 (set of 2 for 2 arms) Powerflex PFR57-507 CONTROL ARM BUSH 996/997 REAR (set of 2 for 2 arms) Powerflex PFF57-801 LOWER ARM FRONT CENTRE BUSH 987/997 (set of 2 for 2 arms) "Caster angle to be adjusted" Powerflex PFF57-802 LOWER ARM FRONT INNER BUSH 987/997 (set of 2 for 2 arms) "Caster angle to be adjusted" Powerflex

After experiencing the difference (Not on a Porsche mind) between standard and Yellow myself; im 99% pretty sure no-one would ever convince me to use black on the road. Good luck.

extanker Posted November 10, 2019 Posted November 10, 2019 there is probably a graph that shows the more you stiffen up your suspension over OEM the less you drive your car on the street . I have seen it for years and many different cars the aftermarket motor mounts,sway bars,springs,bushings,lowering etc quietly go back in their box and sit gathering dust on a shelf waiting to go on ebay
anon_uk Posted November 10, 2019 Author Posted November 10, 2019 Many thanks guys, I have tried to contact the company and will followup tomorrow to make sure it gets sorted. Cheers
