^That picture makes the bottom of the bumper look like it is "sagging" a lot more than it is simply because of the JWT kit intercooler behind it. That intercooler "V"s upward at the bottom which makes the bumper look a lot worse than it is.

The fulcrum splitter has two mounts on the frame that support it. The front uprights tie in higher on the bumper that set the angle. Its a nice setup because it can be removed in a few minutes to prevent damage loading on the trailer.

I know this has been covered, but any thought to giving the 285/30's a shot again after the diff and aero changes? Or would you not have the points (it would only be +1 correct?)?

It came off track with the splitter tucked under/behind the wheels. Dangerous mistake considering he's at roughly 130 -140+ in Nascar's 1 and 2 at CA Speedway.

Nice, can't wait to see the pics. I saw a custom mount on APR's website that sounds very similar.

I guess 285's would actually be +3 now that I think about it.

Zazz93

Why +3? Seems extensive.

I forgot that he is on 255's now +10mm=1 point per.

I think you are allowed up to 275mm w/o penalty, but he gets two points back for being under.

My baseclass is PTB, whose base tire is a 265mm. I get back 1 pt for the 255. To run a 275, its +1, 285 is +4, 295 +7, etc.

My current setup gives me 3 points to play with, so I figured I could use them in the future to run A6s in Time Trials to try and win some free Hoosiers, when I am able to compete with those guys here in NASA FL. I dont really have any interest in running the 275 R6 because as its the same tread width as the 255, just an inch taller, which I think slowed me down, though the tests were done on two separate days.

To me, those jumps seem excessive, 20mm equal 6 point hit. But I guess its the only way to get people to run the cars the way they want the cars spec'ed.

20mm over the base class size is only +4. (+1 for the first 10mm, then +3 for every 10mm after that)

I haven't checked the rules in a while, but the 350z was base classed in TT/PT C. I know with all your motor upgrades etc you would be in B before so much as touching anything else though.

I would agree 100% that the 255 to 275 isn't worth it since they are essentially the same width with the aforementioned gained tire height. The 285's are quite wide though....and short.

Most of the people I talk to say the A is worth at least 1 second per mile. That obviously is ridiculously general, but there is a reason that 99% of the TT guys and all the club level SCCA guys run the A over the R.

What does your car weigh?

I would think from just looking at it...eventually you would want to be somewhere b/w where the T1 and T2 cars are in lap times.....just from your added power, less weight, etc.

How do you find the track records on NASA Florida's page?

Failed to mention....if given the choice b/w 255 A6's or 285 R6's....I think I would take the A6's.

Awesome vids. Seems like threefivezero may have more fun in scca since there are more 350z's to play with

He would probably have to run in STO with that motor build, low weight, non spec suspension, etc he has....that is the land of boosted m3's, vipers modded beyond t1 (unrestricted), and the newly unrestricted, lower weight 430 competition cars that got bumped from t1.

They run in the 2:13-2:15 range around Sebring.....about 10-12 seconds quicker than T2 350z's.

NASA FL TT Records can be found here: http://www.nasa-tt.com/Florida

The Z is in PTC/TTC but rather than take points for all my engine mods (since it would be a ton), I have the car reclassed on weight/whp. I declare a competition weight of 3190lbs, which includes me in it w/ gear (170lbs) and a few gallons of fuel. I use 306whp as my max whp since the motor has worn in a bit and is going to need to be refreshed in June in preparation for Nationals in September. After sending these numbers in, I get a new reclass at PTB and I only take points for my suspension, tires, aero, etc. This method is designed for those who do alot of mods that only support an engine but sum to alot of points.

The car isnt built for SCCA T2 or anything, and I am the NASA Florida PT/ST Director (as of Sept 2010) so its my job to build the PT program. So far its growing well and should have 4-5 cars in class in March at HMS. I am nowhere near the limits of this car and all these news mods will take some time to relearn. Fortunately, this all completes the car for the most part so its just seat time I need.

I dont think the A6s are worth a second per mile, maybe half a second. The problem as I have seen with other racers is that they drop off after 15-20 minutes on a car as heavy as the Z. Lighter cars can get away with it. The car should be capable of 2:25s at Sebring as I work on the nut behind the wheel. Those T2 Zs at the past SCCA National at Sebring that were turning 2:25s dont have the power or aero I have, but they have true Hoosier Slicks (R100s I think) and Motons.

T2 Z's are all on 285/30 A6's. JRZ's seem to be the shcok of choice, but moton, penske, ast, etc can all be found. When I talked with rob hines last year I think he said he was on JRZ 3 ways in his t3 car....those are 10k at least.

I have never run SCCA but we have had many guys come over to NASA from SCCA because they were tired of the drama and politics. I think the racecraft is NASA is awesome, especially the Performance Touring series and Time Trials because you have to pick a car and points carefully. It is better known on the nasa forums as "Pick your frog, live with the warts." Since all the cars share the same rule set, not every car gets the same advantage on certain mods but they are the same points (usually).

Our Spec Miata race group here in NASA FL are all mostly former SCCA drivers who were tired of the unnecessary contact they went through. We still have some rubbing and bumping here in our SM group but nowhere near the carnage of an SCCA race.

There is seemingly ALWAYS a fair amount of carnage at SCCA National events....from what I hear Sebring was no different. I posted this pic in another thread, but this is Marty Grand's T2 Evo (2010 National Champ)...that I took in the middle of the summer last year. Just look at how beat up it is...and this was less than half way into the 09 season.

I was referring to the jump from 275-295 +1 to +7.

03threefiftyz

Especially since they are basically the same size as 285's for hoosiers. Similar to how the 255 is essentially the same width as the 275's. I agree though...the points are steep for that.
