964 shocks/springs need replacing

[rbogh901]

Looking for HD Bilsteins/ HR spring combo or suitable alternative for '91 C2 from someone who has upgraded...thx.

[mike9186]

I am in the exact same boat ('91 C2 Coupe). Not looking to track just street driving. Would also want the benefit of dropping the car to ROW height.

thanks

I have a complete set of shocks from a 93 C2 if either of you guys are interested. Name a fair price and they are yours.

Cheers, James

If your on a budget the bilstein HD h&r red or green is your cheapest approach. I have tried the bilstein HD's with greens, eibach's and reds. I prefer a ride that communicates and handles well around the turns. IMO the HD/red combination is the only one of the three that does this. The eibachs are better than the greens IMO but not by much, but I would not use either anymore. There is little difference in overall ride between the reds and greens until you hit very rough road and more of the roughness is transmitted but IMO it is better than the stock setup for comfort.

I recently switched from reds to hypercoil 2.5" dia racing springs on my c2 for track use the reds had only a few thousand track miles on them and are in like new condition with minor marks that even new springs will have after installation. I am not actively selling but offer them if you need them. $275.00 plus shipping within CON US.

Anyone know what the part number is for the red springs?

[mike9186]

I believe it is H&R 29834

[rattlsnak]

Greens tend to the preferred spring for spirited driving. Nice pricing here for comparision purposes..
Carnewal.com
click on suspension, scroll down to p64, then these: P64 Bilstein HD Shocks and H&R springs

Ive had a few sets of these and they were awesome.

[rbogh901]

thx guys.
Are you saying that Carnewal is the best pricing? I'm wondering who has other sources here and what the proper green shocks and HD Bilstein part numbers are so I can chase them down accurately.

I am running Red H@R Springs.When i asked advice about spring and damper set up, the advice given was to run uprated springs with new standard dampers best combination..This is for fast road use not sure about track use never tracked mine running to higher db rating.

All this will work it is far from ideal. The dampening of the stock shocks/dampers is not adequate for the uprated springs although we are not talking that much stiffer than stock. When I switched over to the hypercoil springs I had Bilstein increase the dampening of the shock to work with the spring rates I am now using.

they usually are slightly cheaper, depends on the current exchange rate. but dont worry about ordering from overseas, they will be at your door usually within 4-5 days. many, many people have used them for years. check out the 'other' board. tha being said, be sure to check out our host's pricing!

Mike,

I can only assume you no longer wanted the springs however a response to my emails would have been nice. I went out of my way and spent time i did not have to collect them for you after you said you would buy them.

[mike9186]

Hi Anthony,

I apologize for the lack of communication, but since I offered to buy the springs from you on Jan 13th I didn't hear anything back from you until Jan 20th, a full week. I assumed that during this week interim you had a change of heart. Unfortunately during the end of that week I went ahead and purchased other springs.

It is my fault that I didn't write back to you on the 20th and I fully and sincerely apologize. I've been busy with a bathroom renovation and it has been taking up all of my time.

I am looking to do the suspension work 'on the cheap' and would've preferred to buy from you.

Thanks for the clarification. I guess my email on the 17th was never received because looking back it does not show as being opened.

A misunderstanding, best luck with the project

I am running konis and Greens on 17 inch twists, the car has been lowered to ROW delivery height and other than that it is stock. I have never tried the reds.

I can honestly say the performance is a radical improvment over stock and I am experienced enough to know that any difference in the 2 would be minimal to me, I am sure both appeal to different drivers but I love the current set up for the track and am constantly amazed at how well the car rides on the street, eats up blemishes on the road like my 4 door Benz.

Here is a shot of what the car does at our local, this under severe off camber turn in and then coming out under full throttle. There is some lean but the forces are maxed in this turn and the car sings through it.

The red and green are somewhat similar but the red will reduce roll considerably over the green. Something about that color that just looks so right.

[rattlsnak]

Greens are stiffer than the reds..

[rbogh901]

looks good. what is the offset on your 17's? 9's? 265's?

btw, somehow i was under the impression that the reds were stiffer.

No greens are the C2/C4 upgrade and reds are the turbo/RSA upgrade. They can be used on either but reds are stiffer than greens. I have used all three greens eibachs and reds. The greens are the softest of the three with the eibachs being slightly softer under normal driving conditions and stiffer in the turns and the reds are stiffer all around.

These are the US rates of the different springs for clarification.
I don't have the eibach rates but IIRC they are F-180/265 R-215/275 or something like that.

Also the rear of the turbo 3.6 is stiffer than and not progressive like the 3.3

89-91 Stock F-158/R-189
92-94 Stock F-169/R-189
91-94 Option M030 F-169/R-263 (progressive rear, working rate)
93-94 RS America F-169/R-263 (progressive rear, working rate)
91-92 Turbo 3.3 F-169/R-263 (progressive rear, working rate)
1992 Carrera RS (European) F-247/R-440 (progressive front and rear, working rate)
1992 Carrera Cup USA F-247/R-440 (progressive front and rear, working rate)

Progressive Fronts and Rears, static and working rates
H&R Green F-190/255 R-220/265
H&R Red F-250/275 R-270/295
