997.1 GT3 Spring Rates

Afternoon all

Does anyone know the spring rate of the 997.1 vanilla GT3 please?

I cant for the life of me find them anywhere on the 'net.

Thanks in advance

I believe they are

front 40N/mm (same part number as the 996.2 gt3 iirc)
rear 105N/mm

Excellent, thank you Sir

What are you looking to do?

Just exploring Steve. Trying to find a balance that I like between compliance and feedback.

I am currently running 60Nm and 120Nm springs on Ohlins dampers, and was curious as to what the standard spring rates are.

This is for a purely road-use car which I know is 'good enough' fresh out the box with PASM but I like to fiddle and tweak

There was a recent 911&PW article (actually, several, about one of their 996 C2s, I think) about spring rates on Ohlins. The guy wanted a good B-road blaster, but Center Gravity's gurus really felt the spring rates were too high.

Can't remember the exact punchline, other than they ended up running something like 40 front/60 rear (ie. half or less as stiff as Ohlins default).

A.N.Other really good makes of suspension run 35/70 for road use on 996/997, for info.

I would be really interested in reading that article. Can you remember what was on the front cover? I'll try and buy a digital back issue version.

Chris F set my car up on these Ohlins. He knows what he's doing for sure.

The ride is pretty perfect for fast A and B roads. It now flows with the road as opposed to fighting it but its too soft for track work. I can set the dampers to fully stiff but then its a little skittish.

Its a compromised set up for road AND track, but its brilliant on the road.

You absolute legend! Thank you

Ohlins are fast gaining a reputation for specifying spring rates that are waaaay too stiff for British roads..

Yep! Chris agrees with you. Ohlins recommended 90Nm front and 140Nm rear. Chris said these would be way too stiff for my desired set up so recommended the 60Nm and 120Nm rates. These are perfect for my for road use but obviously way too soft for track.
