I received my Penske 8300's yesterday. I was planning on running the Eibach front bar, which uses stock endlinks. Will the stock endlinks clear the shocks? I saw a post from Saini when he installed one of the first set of Penske's, and said he had to get heim joints to clear the front forks.

edit, found out The answer is yes, stock endlinks work with an Eibach front sway bar and Penske 8300 shocks.

I will be running 800/700.

Thank you.

Jeff

Do you think anyone uses Showa shocks?

They only make OEM, CR OEM, and Spoon.

I've searched, and can't seem to find it, but what are the STOCK shock lengths from top of shock to bolt eye? (I found the rear, no info on the fronts)

Since many springs are sold in K (kg/mm)
here are the approximate conversions for the poll.
1000 lbs/in = 18 kg/mm
950 lbs/in = 17 kg/mm
900 lbs/in = 16 kg/mm
850 lbs/in = 15 kg/mm
800 lbs/in = 14 kg/mm
750 lbs/in = 13.5 kg/mm
700 lbs/in = 12.5 kg/mm
650 lbs/in = 11.5 kg/mm
600 lbs/in = 11 kg/mm
550 lbs/in = 10 kg/mm
500 lbs/in = 9 kg/mm
450 lbs/in = 8 kg/mm
400 lbs/in = 7 kg/mm

Fronts are never really a issue. If you really want to know ill messure mine. As for the rears my jrzs are 12" and I've bottomed them out. The rear bodys should be around 10.5" to not bottom out when lowered as low as we are.

Awesome! Thanks, this saves me the time of taking my car apart to measure.

RE: Penskes

1) Where to buy?
2) Has anyone had them shortened? If so, how much, and how did they feel after?

I had some Bilsteins shortened on my Miata because of a lack of travel, and the consequent "stepping out" of the rear when hard into a corner and going over bumps. Helped tremendously (along with shorter bumpstops)
