Surely this increases the height that the shock mounts into the carrier?

Since this is your first outing I get it to stock spec suspension and all and do baseline track times and record track times THEN start adding if you think you almost maximized what stock can do. But I agree suspension add insult are key to a beautiful track car that makes you learn. Best learning experience ever 👍🏻👍🏻👍🏻👍🏻. Enjoy!!!

I had a few of these but sold them a couple of years ago. They are now NLA.

With that said, the standard 996 front subframe is perfectly fine. That is what I actually switched to from the RSR front subframe. We went even further on my car and lowered the roll center even more by using the short outer trunnion pin on the RSR LCAs. This helped with improving turning and mid corner understeer.

The rear standard subframes are shared between the 996GT2/3/Cup. The RSR again had a subframe milled with higher pick up points to account for the huge 710 rear tires. I am running the rear RS subframe which for all intents and purposes is the same as the standard subframe. The pick up points appear to be identical or nearly identical but the subframe is milled in areas for more clearance. I do not think there is much if anything to be gained by changing out the rear subframes from the standard to RS unless you want to do I for "completeness" of the conversion. With that said, the rear RS subframe's were actually very cheap years ago if I recall, around $1K for the pair.

The front 997 subframe does NOT fit a 996 tub.

Hope that helps.

I did upgrade to stiffer springs and will have to look up the rating. Another key is the alignment. The car is very sensitive to having the correct alignment which seems like you got that covered

To get around that I would run rear sway bar on the stiffest setting versus one off full stiff on the front. The car is great on track like this. I like a responsive front end and there was too much delay in body control in fast corners with the stock and 400 front springs. The 600 definitely make for a lively front end and it’s not as good on choppy back roads, however it is more than comfortable enough to use on the street IME.

For ultimate handling performance on a track these cars are best with a closer match in front to rear spring rates IMO.
