fahren affair

there's a two-piece 'light weight' replacement rotor for the gt3 made by performance friction. a diy article was featured in "porsche 911 world" a year or so ago. the car in the write-up was a mkI gt3...i'm thinking they might also work on the standard 996.

Rear rotor should work - IIRC they are the same size as the MkI but the fronts are definitely different.

Are you saying put the Motons on with the stock springs? That's surprising but if I can tighten it up a bit with an adjustable shock and still dial it down for the street it might be a good compromise. I just assumed I'd need to go with stiffer springs as well.

I was surprised and disappointed that 2nd gear is non-removable as well...

Hi Bob:

Nossir, we do our own main/tender spring packages and these get tailored to the application: street or competition. The springs must matched to the shock valving and Motons are also tunable with gas pressures.

The Moton's are in a league of their own compared to the OEM suspensions on these cars. Although Porsche has improved the stock components, its really unfair to compare the stock Bilsteins with any of the modern adjustable shocks; Moton, Ohlin, JRZ.

Properly installed and adjusted, Moton's are worth a 3-5 sec improvement in lap times.

Easy now 3-5 seconds, that's allot, maaaaaybee 3-5 tenths to a second lap time just with a shock change.

I have not lapped my GT3 yet but i cannot believe that this car comes stock that lame.

I had Penske double adjustables and they were a great shock on my Z06, not even on that car did i gain a second and the stock shocks are very soft.

How do the motons, ohlins, JRZ stack up against each other in terms of quality and price. I am most familiar with Ohlins (for bikes) which have a great reputation. 3-5 secs does seem like a lot. Waht's your take on the titanium shocks that meridian is selling? Less upsprung weight I suppose.

Thats what I've observed, in my lap times as well as other customers. Certainly the driver is a huge variable but I stand by those numbers. I've used Penske's but I have never found the same degree of improvement that the JRZ's and Moton's provide.

IMHO, Penske shocks require a LOT of work and changes to find the best valving stack that matches the car. Moton & JRZ are FAR better in the valving range and just require some **** twisting (in the right directions, of course). I can only tell you that if or when you get a chance to drive a car like your with Moton's that are properly setup and adjusted, you will be amazed.

I understand your stated concerns here, but I am not given to BS or exaggeration as others who know me might attest to.

CodeRed:

Ohlin's are excellent, as are Moton's. JRZ's are good shocks too, but have suffered quality problems in the past 2 years and we no longer use them very much for that reason. The product support we get from Moton, both in the US and from Holland, is simply first-rate and they really set the gold standard in that respect.

My feeling is that no matter how good something is, its of little value if the manufacturer cannot/will not support the product properly.

I have no experience with those titanium shocks. Unless I can compare them to the current offerings on the track, I'll reserve judgement until that happens. I'm certain they are not inexpensive,...

Z06

You are correct about the Penske Shocks when they come from the manufacture, they were very week, i had them at there full adjustment and that was borderline, i was dissipointed with the valving and i let them know it.

I had a corvette race suspension speacialist revalve them and i got the car to work realy well.

I can not pass judgement on something i have not tried and they could just be that much better on a GT3.

CodeRed

How much does a set of Ohlins or Moton's cost. It seems like you prefer the Motons. Is it easy to change from the track to street setting or does it also involve springs? Sounds like it might be time for a change. Corsas and Motons hmm?

Sloth

Compared the cost of the ceramic rotors, the $1600 is cheap. I would certainly be interested if my ceramics self destructed.

bob_dallas

OK - that makes a LOT more sense...

I'm going to weight in briefly and suggest that the 3-5 second reduction in lap times going to Motons over a gt3's stock setup is mostly driver unless the stock shocks were blown. I own a set of triple adjustable motons for one car, and I've got a set of double adjustable JRZs for another. Very good shocks, yes. But all they can do for you is increase your grip. 3-5 seconds is something close to the equivalent of .2 Gs, ie from crap street tires to the very good R compounds. If you're finding 3-5 seconds making that shock swap (and nothing else) I'd suggest the driver is not driving the stock car to its potential. For what that's worth...

Steve,

Will an aftermarket rotor like the Alcon fit the PCCB hat on the rear?

Larry Herman

And, Z06, will that PCCB hat fit on a steel brake GT3 Rear? I smell a great setup for heavy track use!
