whats a mini "copper"

Why did you move even further from the 964 by adding the 991?
I haven't driven a 996 RS and have read it is quite different to the 996.1 GT3 so don't know if I can be much help. As you've no doubt read the 996.2 motor is more explosive, the brakes (a weak point on track in the 996.1) are better and the suspension is much stiffer - and stiffer again in the RS - resulting in scary moments on bumpy roads and considerable understeer. However it sounds like on a smooth surface with the right technique the RS is wonderfully involving and has a rawness unmatched by later cars. I found the ride of the 996.1 GT3 harsh around town (but good over 60mph) so I think you'd need to be able to choose your roads in the RS. The low speed ride of the PASM equipped 997 RSs is far better than that of the 996.1 GT3 let alone, I imagine, the RS. Whether that extra touch of rawness is worth it when you already have the all-round brilliance of the 997.2 RS (including an even more explosive motor, even better brakes and much more capable suspension), only you can decide by driving it.

A couple of years ago I had a great drive of a 997.1 RS with old tyres that had lost most of their grip on smooth roads in the hills above Monaco. It combined lower grip than that of the 996.1 GT3 with the much more predictable, stable, go-kart flat chassis of the 997 RS, gliding into as much easily controlled oversteer or understeer as you could want with just a lift or dab of the throttle at any point in a corner. I'd like to try changing the Cup 2 on the RS 4.0 to PS 4s for a higher performance version of that easy throttle steering but as the Cup is the only homologated tyre for the 4.0 I'm worried about the insurance cover. Has anyone tried a more road biased tyre on a 997 RS 4.0 or 3.8?

Interesting as I have been thinking the same! Added some grippier tires on my M coupe and that makes the car much less fun on the mountain roads. For the .2RS I am also thinking to change the PS2 with PSS and, if insurances were not a topic, put some 305 like the normal gt3. It looks much better and will be more fun, I am not out chasing the tenth of a sec but fun

I put the PS4 on my car shortly after I got it (11 3.8 RS). I did it mainly for road trips to not worry about rain. Still sticks pretty well with the caveat that I only put a couple of hundred miles with cup 1's on it so cant really compare. Have not tracked but have driven it hard in the mountains and it is a blast. I say do it if insurance not a problem.

My 4.0 came with PSS as the Original PSC's had been replaced and is squirrelly on hard turns. MY 3.8 has PSC2's and has way more traction than my 4.0 with PSS. As soon as summer comes around PSC2's are going on the 4.0.

I had Supersorts on my 4.0 street wheels.
Now that I have 19" track wheels, as soon as my car needs new tires, I would get the PS4 or whatever they are called now but no such luck with 20-21" on the 991RS

Probably too risky for insurance to put a 305 on: I've just compared PS4S to PSC2 and the load rating of the 305 size is 103 for both models instead of 105 for 325 size.
The PS4S has the same load, speed and XL rating as the PSC2 so you would think it would comply with insurance requirements, it's just missing the Porsche N0 rating. My French dealer doesn't want to fit anything not Porsche rated but I'll check with the insurer next time I need tyres.
Squirrelly can be fun. My 4.0 can get squirrelly even with the PSC2s if I get on the power early and hard enough and I love it. I'm wondering whether it would be more fun to sacrifice a little speed for more accessible limits. You have the near perfect means of comparison: can you tell us more about the experience with each? Also how you find the two cars compared to each other. I've always been curious why Evo magazine chose the 3.8 as the best car of the first 200 issues when they had always said the 4.0 was even better.

As an indicator of grip levels does anyone with a better understanding of maths than me know how to compare the contact patch of different diameter tyres? Is it directly proportional to the difference in the tyres' outside diameter? eg. 305/30 19 vs 325/30 19 vs 305/30 20 vs 325/30 21.

99% sure this was because they could not get hold of a 4.0 in time for that article.
They asked to borrow mine for it but, for various reasons, it was not to be...

Mystery solved, thanks. Disingenuous of them that they said they had considered the 4.0 but chose the 3.8.

I thought the same

Anybody have the link to the EVO article? I read it about 3 years ago when it first came out but can't find on the interwebs it any longer...

Plenty available, just at the right price (or maybe wrong price depending on how you look at it). But it does make sense to pick something that isn't a 600 ww production car.

Evo could have said they chose the 3.8 because it was much better value than the 4.0 but they just said they picked the car they liked the most.
