Figured they weren't.

Can you lower on stock perches to add negative camber?

What class do you think this car has the potential to be the most competitive in?

motoring

Super Street is the place. the car is not nationally legal in SSR, but car must be explicitly classed there by the SEB, and it has not been.

Yes, you can lower the car within the factory range, about 10mm

Are shims allowed in SS?

Yomi

My reading of that would say yes, if Porsche tells their shops to officially do this for customer cars of that model and year, and especially if they supply the shims or eccentric bolts. I'm not sure which tech manual one would have to produce to prove they were legal (wouldn't be an issue except at national events), and my guess is that this means $$ Porsche shims not third-party ones (it might depend on the exact wording of the tech manual, and now it really shouldn't matter unless you're fighting over a national event trophy)

I'm looking to order a Longacre 2.5" gauge today. I'm going to go with liquid-filled even though I read it's not completely necessary since I read the regular Longacre ones are more than sufficient.
Should I go with 0-45 or 0-60 psi? Does it even matter?
0-45 is like $10 more.

Yomi

Not sure if we'd ever see it with our cars and current tires, but on some cars not that many years back Hoosier pressures were 40-50 psi. A meter that maxed out at 45 psi would be a bummer for those.

Longacre recommends "All tire gauges work best in the middle of their range." on their site. That would indicate 60 psi would be good for standard auto tires. [ref: http://www.longacreracing.com/techni...spx?item=8183]

My next race is June 19 Yea I personally would be running anything close to 40. I was thinking that 0-45 would be easier to read since it would be bigger, but after that last quote I will definitely be going with a liquid-filled 0-60. Thanks!

For those of you that run a second set of wheels and tires, are you taking them to the event or doing the swap at home first? I ask because in my old auto-x car I could put my v710s in the backseat and my jack and tools in the trunk. Don't think that will be possible once I pick up the GT4.

So, do you commute on competition tires? Trailer the car? Tire tail? Something else?

Looks like the GT4 has been reclassified to SSP. Bummer

Already covered. (note that is from last year)...

Yes it's SSP if modified to SP allowances. Stock, it remains SS.

thigos

The amended section showing it in SSP is from April of 2016 (see date at bottom of page 31/52), even though the original doc was from Nov, 2015.

Here, in Feb 2016, they amended, putting a stock GT4 in SS. page - 9

Then in April 2016, they amended appendix A again, putting a stock GT4 in SSP - page 11

Seems pretty clear cut to me. I hope I'm wrong though. Is there something else more current showing it in SS? This is the most current mention of anything relating to the GT4 that I have found. If you could provide a link showing something otherwise; that may help some of us out in regions that are putting us in SSP.

motoring

It is specifically classed in the 2016 rulebook in Super Street. http://cdn.growassets.net/user_files...pdf?1468011553

thigos

I am definitely confused, the car is shown in both places - SS on pg 164/345 and in SSP on page 184/345. Is this normal for a car to be eligible and listed in multiple classes?

If I wasn't consistently winning in SS, I'm sure my region would not have brought it up. How do you guys suggest I explain my case? Thanks for the help, autox is a new type of racing for me.

Stop being so good!

The car is classed in SS for Stock and SSP for Street Prepared. If you change springs, headers, wheel widths, etc. you would run in SSP. It used to be classed in ASP (I believe) for Street Prepared and they moved it to SSP.
