You'll have to call Alvin, my tuner, to get the answer to that. I am not sure of the details.

I keep telling the girls if they opt out of college (better not), then I am going to have one helluva ST1 car. LOL.
As long as Danny Popp doesn't show up, all you would need to do is add a $500 racing cam to win ST1 nationals...

FEEDBACK on the new setup:

We hauled all the way to Watkins Glen last week for the NASA NE (vs SE) event and had an absolute blast. Beautiful area, great racers, and awesome track!

- The Wilwood W6A front kit and W4A rear kit with Carbotech RP2 pads on the 6627 backing plates performed flawlessly. I personally never complained about the stock Z06 brakes like a lot of people, but I really like the new kits. Brake pedal feel is extremely firm with zero sponginess. I was braking harder and later than ever before.

- The Pfadt Featherlight single adjustable coilovers, with upgraded springs, felt better than great. ZERO nose dive under braking, zero "float" through the apex, and no rollover on corner exit under acceleration. I actually think the coilovers did more for braking than the BBKs. With no nose dive under braking, there was far less massive weight transfer to the front and I think that helped braking more than anything else. Even though the springs are heavier for aero later and I am still running no aero, David went with the recommended settings from Pfadt and it felt great enough that I never felt the need to mess with it.

- The spherical bearings helped a LOT too. I am not sure how much of the improved feel can be attributed to the bearings and how much to the coilovers, but the car feels very responsive and easy to drive now.

After learning the track Friday morning in a couple of sessions, I started getting the hang of it and was running 2:08s by mid-afternoon. At one point late in the day coming through T9 back onto the NASCAR cut-through, I actually thought, "Damn, this thing feels FAST! Faster than it has ever felt."

I did not realize how hard I was driving the stock suspension in order to stay within sight of the rest of the C5 Mafia. I have been tracking this car since 2009 and have felt for the last two years that I was close to the limits of the car (in that setup). My laptimes over the past two years have not decreased and was always curious if it was me or if it was the car. I am now certain it was the car. During the Thunder Races on Saturday and Sunday I pushed the car harder and harder and started sliding the car on old A6s and it still felt really good. I am actually going to have to address my driving style and skill to find the limits of this new setup.

Looking forward to the next track outing on a track I know to see where it compares. If all goes well with some repairs, I will be at Carolina Motorsports Park the first weekend of November with a set of sticker A6s.

By the way, thanks to everyone that stopped by at Watkins Glen to chat!!! I wanted to spend more time talking around the paddock, but a fuel leak and an oil leak kept me busy. As well as catching up with my Canadian friends.

So only difference was poly bushings? What else didn't you have?

Huh? Who the heck had all that stuff?
I thought we were all on pretty much the same TTA/PTA setup other than your bushings?
BTW - that wasn't a dig. I was just curious.

In 2012:
You, Mark, and Morris had poly. Pretty sure Rory and Ziggy had poly as well.
Morris had aero.
Rory had a brake kit.
Brian had a ducktail spoiler.

Not to mention all of the times you guys threw extra parts at your cars and ran in TTS/ST2.

No jab taken. BTW, I did vouch for you and told that guy to buy your four wheels vs my two if he was wanting a full set. I guess the fact that mine are bare and ready to ship swayed him.

I don't know why I'm complaining about being busy with work and not being able to work on my car, a quick look back in the past shows the same was true in 2010. I (started) to put the Pfadt poly kit on the car after either the May CMP or Roebling event in '10. I remember because I never had time to really work on it, and for several events I'd just do a few bushings, run out of time, align it, go run.

I don't remember all the combos but I remember running Charlotte with like a poly on the rear lowers, and poly on one front lower, and the rest rubber. Even in march of '11 at RA I still don't think I had it done, I had some delrin shock bushings and some rubber

I have the crappiest C5 in the SE currently with old school PTA poly and stock exhaust still dragging around the sorry '01 motor

A couple of hours worth of work and the following have been removed:

- OEM manifolds
- OEM midpipe with cats
- coil packs and wires
- spark plugs
- EGR/air pump hoses, brackets, and hard pipes
- alternator
- starter
- tunnel plate
- coolant temp sender

All in preparation for the Kooks Race Long Tube Headers and Mid-Pipe. Calculated savings are 28lbs, most of that in the midpipe. 3.5lbs in the egr tubes and brackets.

I stopped there because I am going to replace the hard fuel line from the tank to the rail. At Watkins Glen, one of the braided clutch lines rubbed a hole in the metal fuel line and caused a leak right onto the midpipe. Came very, VERY close to going up in a ball of flame.

Here is a pic of the trackside repair:

I need help. I received the boots last week, but the vent tubes weren't in the package. Today they came. I have two boots, but they sent me 6 little straws. Do I use all 6? I think I only need 4. I used tape where the axle would hold the tubes. Did I do it right? Your help would be appreciated.

I did not buy vented boots, but what you have shown is correct in my opinion. Maybe someone else will chime in if they think differently.

Here's some updated pics. I think I need to cut the straws to just aid the boots passage. I'll wait for some imput before assembly.
