upgrade my coil springs

Recommended Posts

Hi Loren,

I would like to upgrade my stock springs and shocks for my 993 targa, what I have right now are the stock springs w/ red color code and the green colored shocks. I am planning to get the bilstein HDs w/ extra adjustable threading in carnewal.com and would like to customize my suspension by installing a double spring set up w/c means a spring set w/ the tender springs but to do this I have to give the spring supplier the exact free lenght of stock springs and inside diameter to know how to match it. Would you have this specs of these stock springs? If not, do you have any reccommendations? My purpose for doing this is to lower my car only around 3/4" to 1" w/c means not to low, 'coz getting H&Rs or eibachs means I have to lower more than 1". Also, since The roads where I live (Philippines) are really bad I only want low spring rates w/c is only around 175lbs to 200lbs./inch fronts and 300lbs to 325lbs/inch rear. looking forward for your enlightenment.

The springs you have are the lower RoW springs and the only springs Porsche recommends for 993 Targa.

Send an email to Gert at Carnewal.com and see what he thinks. Some of options will vary by model year as the later cars can go a little stiffer without chassis problems.

Thanks for the quick reply, we spoke just yesterday he is recommending the m033 springs w/ the hds. he said the m030s just way to stiff for the chassis. But what I wanted to know is there any other options where in I could put a double spring set up (main spring w/ tender spring maybe 4") w/ the same kind of soft ride w/ minimal lowering height? I tried asking H&Rs they want me to ask nilstein for the required spring height then I called bilstein they dont know the stock height of the springs. Anyway, just want to have that option 1st if posibble and also would like to hear your opinion, if not then probably I would just go w/ Gert's recommendation w/c is go w/ the m033 springs.

I think you really want to use a matched pair of springs and shocks. Otherwise you could get shocks bottoming out or overextending.

I personally would go with what Gert recommends.
