Wow, what a fascinating topic! You guys are extremely knowledgeable about this... Would any of you recommend some good literature to learn more? Possibly related to porsches and to be wishful, maybe even 993s?? Thanks...

Arun,

The best place to learn about this is factory manuals and online forums (Rennlist, Pelican Parts). To my knowledge this topic is not well covered in most retail Porsche enthusiast books.

Doing your own alignment - and driving different setups - is the IMHO the best way to learn about these things.

It's useful to own a kinematic tool, or at least ensure that your shop has one .

Thats why I am going to 9" wheels on the front with 255 tires..... Much more grip...

Matt - Yeah, I've got the factory service manual and 993 essential guide that really helps me through stuff, not to mention this forum. The factory manual goes through how to physically adjust, remove etc. But I guess, I am looking for something that explains why from a cause/effect perspective. The graphic that Bill put up seems very educational. Anyway, I'll let you guys get back to your discussion and see what I can't pick up as an observer. Thanks...

Steve - 9"/255s on a light set of wheels sound like damn good solution

Yes, I'm switching to 8.5"s w/ either 235/40 or 245/35 for the front, I had 9"s but didn't like the fit.

Please post pics and let us know how the 255/ works out. Seems kind of too big to me but what do I know

I hope Cris can post some pics of the leading leg bush, it sure does look like the leading leg bush is a monoball, just covered in rubber.

I didn't know that, it's sure great to learn something new

When I was running 17" wheels I was running 255 up front and 275 in the rear, the front end grip was amazing, turn in was almost instantaneous the car just reacted beautifully to any steering input.

I will be running 255/35 on the front and 285/30 on the rear. As soon as I get the wheels rebuilt and the rubber arrives I will post pics.....

Agree the extra rubber makes a big difference

I can't live without my 285 front and 335 rears Sadly this requires a few "modifications "

Is winter over yet? Can't wait to get it out of hibernation and start tinkering again.

Stupid salty roads

Don't even get me started, it has been below -20c for the last 2 weeks........

To the OP, Rennline just announced a deal on all of their monoball links, replacing Camber, KT and Toe for $1150.... pretty good deal.
