H&R coilovers going in now! - how do I determine height of rear sway link mount??
Guys I'm currently in the process of installing my coilovers. How do I determine what height the mounts for the rear toe links should be at?? I am reusing the stock link as per H&R instructions.
(Sorry for the awful camera pic)
Thanks in advance

Measure from the center of the bottom mounting hole in the strut to the center of the mounting hole for the sway bar link (at 90 degrees from each other) on your stock strut, then duplicate that. If I recall it's about 90mm.
GT2 spec per the manual is 105mm if you want to shoot for that as well.
The sway bar should tuck up about parallel to the control arm when on the ground.
Biggest thing is to have both sides exactly the same so there is no preload (side to side) on the sway bar when the suspension is weighted.
I had measured with a caliper from center of shock mount hole to sway link mount hole on the stock set up. Then I basically tried to duplicate that on the new setup. I don't think it's possible to be exact. I was hoping there was an exact measurement from H&R. (Guess that's why many run adjustable drop links)
Anyway, I've decided to call it a day. Left & right stock rear shocks/springs are out. And I have assembled the H&R's to the perch height as per their specs. Ready to pop them in tomorrow morning...then move on to the fronts....
Make sure you seriously tighten the hell out of the bracket locking collars. You will need two spanner wrenches the you use to counter each other. They have a tendency to come loose and if they do, they will come in contact with the axle or turbo intake pipes.
Pwdrhound, thanks for the tip. I will tighten as much as possible.
Vogz, yes these are H&R Street Coilovers. I did a lot of research before buying these. I am building a fast street car that might see a very occasional de. I was between H&R Street, H&R RSS, PSS10, and Ohlins R&T.
I contacted all three manufacturers and from the information they gave me (as well as info I got from forum members) I determined that the PSS10 & Ohlins when installed to manufacturers specs would only lower the car about 20mm. I'd like to run around GT2 height so 20mm is not what I wanted.
The kit looks extremely high quality and the shocks are made by Bilstein.I plan to upgrade sways, do a corner balance, and a more aggressive alignment on the car.
My understanding is that these should ride extremely well on the street, give better performance, and still give me the ride height that I want. I believe these will do the job I am looking for. I will update with my impressions once it's all buttoned up

Too soft for a 911 suspension upgrade IMHO. The spring rate are only a tiny bit different than stock. They are significantly softer than GT2/3 stock. They ride nice, but are obviously designed for lowering more than handling.
I want a real nice ride on the street as my first priority, lower center of gravity is also a priority for me Also, I'd like to get a good alignment and lower the car to about gt2 height. I don't really think there are much other options that will do both of these things at such a reasonable price. They will perform better than stock and obviously much better than just putting on a set of lowering springs. For my particular setup and for anyone with similar goals I think they will be perfect!!

Don't get me wrong, the suspension is good quality. If that is your goal you will be happy.

I ran the H&R streets about 5 years ago on my car. It's a great suspension for the money and it's excellent for the street and the occasional track day. I would recommend it over PSS10s any day of he week if you want something simple that works well at a lower GT2 ride height.
