Drove my 964 RS to Marbella and left it there for a year , the Sunday mornings were never the same on the Ronda road . What a country to drive in . Amazing roads open spaces ... and some nice tracks
Ascari turned out to be wet for the whole weekend(!) contrary to what the southern location would have promised. But it was illuminating to sit with a couple of friends in 996 cup and GT3 cars with wet tyres. Wow - blown away by the level of grip of wet tyres. Almost like driving with dry grip.

What a fantastic picture (of a fantastic car)!
You've probably previously been asked what equipment you use but I'm particularly unlucky when it comes to searching forums, and re-reading stuff (as distinct from being bone idol).

Usually a Nikon full frame DSLR - used to be a D600, now a D750. Most photos are with the accompanying kit lenses. However on the Iberia trip I tend to hire a couple of additional lenses for fun. The photo you referred to was taken with a wide angle 14-24mm f2.8 lens.

Lovely upgrade. It will make a big difference. Please report back on your perspective
You're asking the wrong guy. I will try to understand the difference though. 
I was worried because the Cup diff plates aren't available from Porsche and even talking to Carnewal when I ordered new harnesses the other month, he could no longer get any. In any case, a very useful chat with Steve at JZM and he persuaded me the plates would be useless without the ramps, both of which he had stock of and was happy to take my money for...

He never said that when he didn’t have the ramps to sell...
I’m not convinced you even need the ramps ....But then again, plenty of 996 GT3 owners didn’t need KW V3’s when they asked for a geo/corner weight/ride height adjustment either ...

), on a 997 if you're going to replace the diff plates you probably might as well replace the ramps to get the 996 locking ratios for the full works.isaldiri said:

And yes, KW's were discussed too.

IMHO as a mechanical engineer, as opposed to a driving expert, I can see very good reason why ramps are better. The plates only act when the loads from the ramps actuate them.

I bet they were !! And had you expressed ANY interest whatsoever, you’d have rapidly moved onto the Manthey KW’s Lovely, clear explanation here, for people following this who might be idly curious about how these things work:https://www.youtube.com/watch?v=PEdnH7_7_yc&t=87s

When you ramps Digs, did you mean THE ramp? ? I ask as your post indicated your 997 diff doesn’t have ramps already fitted ??

KW's were Manthey ones, FWIW. I do like the idea of them, but need to accumulate funds...

Put my PCCBs into storage last year and fitted Alcons which work well and have decent modulation too.
A bit O/T but any reason you went with Alcons over say Brembo or Giro?I'm sure there are a variety of other steel brake solutions that are equally good though. I do find steel less binary than PCCB. The latter were hugely powerful, but on some corners, ti was a bit too easy to trigger the ABS.
This cold be personal preference; I tend to run Hope hydraulic disc brakes on my mountain bikes, rather than Shimanos for the same reasons; locking a wheel is okay when you're scrubbing a load of speed off on the way into a faster corner, but it will put you in hospital if you lock a front wheel on a very steep, twisty, technical descent.

yes, the 997.1 GT3 ramps, as standard, were relatively 'weak' - as in they did not intervene as aggressively as either 996.1 or .2 diffs. The engineers had decided to 'use' the ABS to do some of the work, but this is neither as dynamically efficient and also creates a lot of excess heat and wear on the rear brakes when tracked.

Ah, from your post I thought you were perhaps suggesting the 997 had no ramps as standard.KW's were Manthey ones, FWIW. I do like the idea of them, but need to accumulate funds...
You can increase the pre-load on the 997 diff with thicker/stronger Belville washers, and the Cup plates have a far larger surface area/high coefficient of friction too.
I’ve no doubt the 996 ramp angles are better, because as you’ve said, the 997 relies on electronic wizardry to perform a large part of the traction/stability.
