M30 ROW Suspension Question

[Steve N]

Some years ago I purchased an M30 ROW suspension kit from Suncoast and installed on a 99 996 C2... I've since replaced the 99 with a lower mileage 2002 996 C2 and swapped the suspension over from the 99 to the 02... Suncoast however indicates that the kit is different for the 2002 and up 996s but all they can tell me is that the spring and shock part numbers are different...

Loren/JPA or anyone else out there have experience with these kits and have I gone down the wrong road in putting an early 996 kit on a 2002 996???

thanks/steve

The Mk II 996 series (2002 and later) have more chassis stiffening than the previous cars -- and weigh more.

So spring rates need to different - just as they are different between a 6 speed and Tip and different between Cab and Coupe.

Weigh/un-spring weight determines the spring rates and then the dampers need to match the weight and overall suspension travel (bump stops).

Likewise you will then want the correct diameter swaybars to finish the "tuned" suspension. Porsche's standards are neutral handling - but you can always adjust or swap swaybars to get more or less oversteer and understeer.

I would highly recommend starting with the Porsche spec'ed parts and setting and then work from there.

Thanks Loren, good advice... and my apologies to JFP who's handleI fat fingered badly above. That will teach me not to send out stealth emails from work when I should be... well, working!
