Street friendly racing suspension mods.
i must be blind - searched it back and forth, cannot find it. What was the topic name, do you remember by any chance?
I am trying to decide specifically right now between PSS10, KW v3, JIC CROSS.
JIC models are not quite clear to me yet, I found several good reviews and in one it was noted that JIC has 14 positions, then on JIC web site I do not see anything with word 'CROSS' on it and it shows models with 10 positions and 15 positions, well, will look further. It is fun.

Best I could find with a quick search.... its from a thread in the 997TT forum but its not the one I was looking for.
Bottom Line: Bilstein PSS10's are a proven CO design that is probably the most popular with Porsche owners. You cant go wrong with them. Are they the most aggressive track CO, NO but they are a great compromise between a competition CO and a street CO. If you want something a little more focused go with KWv3 or make the jump to some Motons, JRZ's.

It is quite interesting - I spoke to several local Porsche tuning shops and they all advised on PSS10 only.
Total install price to do this in a shop was quoted $1K for coil-overs, $200 for subsequent alignment and tuning, seems to be standard across all shops.
But no one advised nor recommended KW. Is it a new brand or why would that be? The only preference I see toward KW v3 is that it is sort of like best deal on it is $300 cheaper than best deal on PSS10.
So, should I stick to PSS10? Or try KW?

Doesn't coilovers need to be rebuilt after certain miles? Or that does only applies to the el cheapo ones I've come across haha.
Why is lowering springs not a good option for a street car with a lil' bit of auto-x, are the shocks subjected to blow out? How long can you usually run on stock shocks in such a case?
Thanks,
Mike

Brrrrp! Game over (I think). The Bilstein's recommend a minimum lowering (from memory) of 10mm. I believe that most aftermarket coilovers have similar specs. Most installs lower the car further. 20 mm would be a good guess re the average.
If you are bottoming now (those MA roads), this simply may not be viable.

So, do you exclude H&R for any specific reason? Or are they, essentially, just not on par with PSS9?
I am very concerned on how low car will go with PSS9 and Eibach. Right now on bare stock I cannot drive my kid to new school as they have very steep angle on drive-out. Such a bummer... This long front on 997 really makes life harder than it should be.
PS. does anybody have a link to coil-over step by step install manual? I may find some torque guidelines from workshop manual but it does not seem to have detailed section for suspension assembly for some reason.

I don't think you can go wrong with either choice.
All of the mentioned products will make your car look aesthetically better although a few of them will actually make it handle better. We always suggest adding adjustable sway bars first, proper links and a good alignment done to the proper specs for what you are trying to do.
Doing suspension modifications in steps is great way to figure out how your car works and a way to save money in the long run.
In racing, getting a car to work correctly is key. When we develop swaybars for a car(proprietary design done to our standards) we go through many different variants attempting to get the absolute best from the parts even at the cost of making 1 set up swaybars at a huge amount.
Buying parts that work well as a whole is quite key.
We sell packages where all of the parts are designed to work together... from mild to wild. Here are stages 1 2 and 4.
Stage 3(not pictured includes revalved bilsteins, that we respring here.
