Any Rennlisters from New Zealand?

Speaking of brakes, what do most folks use for rotors? I'm a bit confused by the difference between genuine Porsche, and OEM, and whether it really matters. Do you guys use Sebro or Zimmerman or what? Needless to say my indy says only genuine Porsche...
I don't want to compromise in anything to do with brakes.

On the SITT I took a set of road tyres for the track. I was slow but it was great fun. Less grip let me really feel the car. Steve reckoned it is a great way to get the measure of the cars handling and experience with it on the edge before adding giant grip. The few times I've accidentally redlined/hit or neared the rev limiter I don't like it (usually alongside John heading for a corner). 24 year old engine, can't be good for her. I'm not really that interested in lap times at the expense of shortening her life. I think it's why I love quick and slow road trips.... You just can't do the same level of thrashing the car but you experience it's soul, noise, roughness and the pleasure that comes with all of this in beautiful NZ scenery.
My son, after "looking after" Lola in Wellington for 2 weeks for me (could not believe his luck) said getting back into his Mazda back here in Auckland was like "driving in cream" by comparison. Ha, even the power steering on a 964 can be hard work :-)
Dave, you are going to have a hell of a lot of Urban Outlaw like driving fun.

too right Doug,
Also nothing like no power anything (steer, brakes,) to really feel whats happening to the car and that's what is good about the older cars - and the fraser. Added to that the lightness means that it doesn't feel inclined to bite when or if things do get a bit hairy. I reckon this is what you feel with between your older vs newer cars

Based on the SITT I suspect we would have to start very close together to be dicing it up on a Playday session as we're talking minimal lap time differences, so fending or chasing would be a conscious decision on one or both of our parts. That's the beauty of the AIM Solo - you don't need to compete wheel to wheel to know if you're improving. For my part I'm determined to break 1.19.50 at least once this season. Based on last year it will be a first session run on a cold morning that sees the best times.

Since we were the only car running double duty for the whole week we needed to make sure we got to the end. So the agreed rules were no 2nd gear in any corner, (anybody with gear change issues its normally second right?) and 6000 rev limit. George had to get reined in over revving on the straight at Teretonga and I have to confess a few times I ran to 6500 but never did use second, even out of the tight right hand infield hairpin at Levels. Just had to be smooth as possible and not worry that second gear might be half a car length quicker.
There is nothing like losing 5-7 car lengths on the straights to focus the mind on smooth and accurate cornering to try to catch the 993,996 and 997 boys on the corners.
Tell you what though if the engine ever needs to be opened up its going to get some mods haha. I'm not competitive...

Apart from the weight it must certainly benefit the handling that your CoG is 500mm closer to the ground than in a typical 911. I watched you corner and compared to us you were totally flat! It cornered faster than anything in our group....

No expert here, but I believe the red car had Zimmerman rotors. The came to me already on the car and well used and I went through 2.5 sets of pads and one skimming. as far as I know Doug has carried on with them riding under the new Endless pads. They were really good. I imagine genuine rotors are even better though.
Anyone else got a view on rotors?

I reckon there's a nice little bit of sparring brewing behind the 993's there. Doug stepping up to Hankooks for the next serious HD session will be interesting times in the Herman household.
John. If you need to find another 0.5s in case Doug gets serious then I suggestion that modification I told you would have a sure fire result to your lap times 100% guaranteed.
Prestigio!

Check out the 964 board for feedback on Zimmerman rotors. I recall researching this for 993 and the consensus was teh factory rotors were of better quality than after market for not alot more $$$. That said I know a number of UK and German guys who use after-market drilled rotors on the 964 for track work and swear by then with SFR and race pads (dont warp when stationary as holes allow gas to escape etc). "Drilled" rotors certainly look better but for all out track work Im guessing slotted are probably more durable...

I still dont understand that. I find I get faster and faster during the day. Im sure a fuel tank emptying itself during track duty is partly helping (weight wise). Maybe its the fact I've driven every track in NZ....once LOL! I reckon there's a nice little bit of sparring brewing behind the 993's there.

Macca weight (lack of) definitely helps a lot. Car can be set up softer but still not roll very much. Disadvantage relatively speaking though is that unsprung weight relative to total mass is more hence inboard shocks to get unsprung even lower.
The very short wheel base means any rotation over steer can be quite quick. In the dry you can feel the steering weight change (no power steer) before your bum feels the oversteer so its manageable.
But in the wet its very snappy - hard to turn in with no weight on the front so understeer and then snap oversteer. Its not much fun in the wet anyway with no lid or screen

re rotors
Not sure about fitment for different Pcars but I use DBA slotted on Targa car. I think 5000 on front and 4000 on rear. They take an absolute pounding and have paint stripes so you can see what temps you have achieved at max heat. Drilled rotors will have cracked between the holes well before the slotted rotors need to be replaced. DBA also cheaper than Brembo/AP equivalent

Graeme. Those dba rotors look really impressive. Made downunder too and with Porsche fitments (at least for front rotors). I think these would be worth trying for the RSG track enthusiast.
