So I'm thinking about upgrading to coilovers on my '02 C4S and I was wondering if anyone has any experience with the H&R Street Performance Coilovers.

I know a lot of people recommend the Bilstein PSS10s but they are about $1000 more expensive and I never really hear anyone mention the H&Rs. I daily drive my car, do spirited backroad driving when I can, but I don't track it so if the PSS10s are only slightly better I don't think it's worth the $1000 price jump. I'd like to retain decent ride quality and some clearance for speed bumps, etc. Any feedback is appreciated.

I was also wondering what other suspension upgrades should I consider while I'm at it? I was looking at front and rear H&R sway bars.

You also should factor what kind of ride characteristics you like. For me, I find the PSS-10's a bit more damped and thus a little more refined on various bumps over the H&R which is a little more rough around the corners and slightly harsher on some types of bumps. If you plan on keeping this awhile and you are daily driving it, you should really ask yourself if that $1k difference spread out over time is gonna bring you more enjoyment. The last thing you want is to regret getting in your car everytime because you didn't get that "other" coilover. I would see if you can get a ride in a member's car that has both of these and decide for yourself.

 

Ive had them them a few years now. Great on racetrack or smooth backroad. Dreadful on city streets. I have tarret front camber plates which doesn't help, no dampening. Coil overs are a compromise and I've learned if your not ready to do adjustable LCAs plus bones, links, etc its probably better to refresh stock. Or do springs and bilstein struts. I'm in it already so I'll continue to upgrade suspension till it's right.

 

Installed them on my 99 C2 last week. $1700. Superior turn in. A bit harsh on rough roads. Could not achieve all factory spec alignment. Could only manage -1/2* camber front, -2* rear ( vs 0* and -1/2* spec). Toe and caster spot on. I suspect tire wear will suffer a bit.

 

Installed 4 weeks ago, along with H&R sway bars. Exact same experience as Mike A! Tracked car once - felt really good. Don't mind the rougher ride on the street. They are not PSS10 - good enough for me!

 

I have H&Rs on my 2002 C2 and I love them! Ride hide is not too aggressive and honestly looks the way it should have come from the factory. The ride feel is tiny bit harsh, but I like the feedback from the road... I purchased my from Achtuning

 

I've got them on my car , installed last year .
I wouldn't describe them as harsh at all even on Vancouver roads , certainly better than a sport shock and stiff spring set up . Any coilover is going to be stiffer on bad bumps than the stock set up.
For a street car I didn't need the full adjustability of a more expensive coilover ( and in the past I found once I set up a coilover I didn't adjust them again anyway)
I like them , they are much more comfortable than the rss club sport h&r co .
I'd reccomend them to anyone except Boulevard cruisers. I also used h&r swaybars and a full set of powerflex bushes . Even if you keep stock bushes make sure they are in good condition , any sports suspension is going to increase loading on your bushes .
I also used new stock top mounts and gt3 drop links

I Had my alignment set up just on the aggressive side of the factory specs without issue.
Tire rack seems to have the best prices on them.

I'd love a set of ohlins but for the money , h&r are a good upgrade , and German made , better than offshore made units.

 

I need new drop links for H&R coil overs - you mentioned -GT 3 where can I get those?

If I was doing it again I'd use the tarret engineering adjustable ones . And they are cheaper than the gt3 ones

 

How come any coilover will feel stiffer on bad bumps?

 

Any sport suspension , be it mo30, eibach springs & koni shocks or any coilover will feel stiffer and not as comfortable as the stock suspension on a really bumpy road because they will all have higher spring rates and damping loads .

The stock suspension is comfort biased for the majority of Porsche owners who never try to get the most performance out of their car . That's why mo30 was a factory option for the more performance biased customers.

Those adjustable drop links

If you drop the car the minimum , about and inch , you can use stock ones

 

I replaced my previous coilovers (Techart) with H&R since my shocks had worn out. The difference was definitely noticeable. The H&R coilovers are slightly stiffer but they don't seem keep the wheels on the road (over bumps) quite as well. I'm still happy with them though.

My biggest complaint is that the height of my car is slightly lower than I'd like and I have it set at the top of the range. They allow you to lower the car substantially, but the usable range is pretty small. I've had my car quite low in the past but I got tired of having to slow down to go over dips in rough roads.
