So I bought the Penske single adjustable shocks from
Fred/BWR last fall and (finally) installed them on New Year's Day... the whole "operation" took less than two hours...
All I have to say is OMG!!!
Originally the car came with the LSS sport suspension option and after nine years I thought they were pretty good shock/spring combination. WRONG!
I set them up as Fred suggested at 20 clicks from full hard (FFH) front and 40 clicks FFH rear. That along with TurboPhil's ride height recommendation of 120mm front, 130mm rear turned out to be perfect.
Here's how my inaugural drive down my favorite switchbacks went... it's 2.5 miles each way. 15 - 35 mph speed zone throughout. It's the closest thing we have to Phoenix's Hwy 88 here in Kansas... 18 turns ranging from 30 degree sweepers to a 140 degree mini-hairpin...
In nice warm Summer weather I could drive it 25 - 50 mph with either plow understeer or sliding oversteer limiting me with my all season street General UHP's.
So it's January in Kansas and an uber chilly 18 Fahrenheit degrees... AND I drove the exact same route in the Penske's at 35 - 70 mph with absolutely no drama whatsoever. It's like my tires suddenly have grip. So much confidence... SO much corner exit rear weight transfer and stability!
I also drove over three sets of railroad tracks on the way to the road. Couldn't barely even feel them.
Summary: Best money I've ever spent on the car, hands down.
I know I CAN change front/rear [rebound/compression] settings but right now I'm still lavishing in rambling OMFGitis... Perhaps I should have held out for this new non-adjustable configuration...
Can't believe I forgot to mention that the SA Penskes are 2.39 lbs. lighter than the stock LSS shocks. That figure includes all hardware. Very Happy!
