I have no interest in the cost of Hoosiers, plus I live close by so I just drive to LRP.
I've got a video up on youtube if it helps you at all. The best tip I can give you is to get back to full throttle sooner everywhere.
How I am missing you? I'm in black run group and I've been to every CVR LRP event in '16! The only GT Silver I've seen is Alex. Make sure we meet next time!

Just did first two days with the GT4 with Metro NY, April 29 & 30. I'm leaving the RE71rs on the car for the street as well. HooHoos are stupid $$ for DEs!
Thinking about booking a day soon with the Club and a coach to get on top of this puppy! Its way better than I am...
Where do I find your video? Always looking to learn!

Awesome stuff. Please post your LRP video link so I can learn your GT4 lines and mimic them. Sub-1:00 at LRP is my personal Everest. Got down to 1:00.4 last fall in my 991 Carrera S. Hoping to get that next half a second with the GT4.

Waiting on a Bluetooth OBD2 module so I can capture throttle and steering data on the overlay so I'm not sure how helpful the video will be but here it is:
Joe sorry for derailing your thread here...started out with RE-71R tire pressure info on the previous page I swear!

It sounds like you were in third through Big Bend, the Left Hander, the Right Hander, then up to fourth on No-name Straight, stayed in fourth through the Uphill, West Bend, and the Downhill. Is that correct? And then did you shift up to fifth on the front straight, or do you just get to redline in fourth before hitting T1 again?
BTW, love the "woo!" at the end...

Previous laps I was only using 3rd and 4th and was running out of RPM on no name in 3rd and main straight in 4th. As my corner exit speeds increased I was hitting the rev limiter so I had to use 4th on no name and 5th on main. Since the power falls off after 7000 it turns out the time wasted shifting is still faster...go figure!
I've got my lap timer wired into my Stilo helmet communications so I can get my times without having to look at anything. It works great except I forgot the mic would pick up my voice! The "wooting" continued up until left hander in the full video.

Long time no talk BTW! I see you are enjoying the RS! How's my steering rack doing in your RSA? Don't see you speak much about the RSA anymore(or perhaps I'm not looking in the right places!)
What's wrong with the uphill?

I plug in my IPhone to 12V, use a Imvio case with fish eye.
Via Bluetooth with GPS amplifier on the dash as well as the OBD thing for extra data, but doesn't do much, see my video.
Go Pro I phone holder with a big GoPro Flex Clamp thing to clamp it to the CF part / harness holes in the seats.
Works OK.

Had the front wheels re-balanced with the weights on the inner barrel and mounted all 4 wheels today.
![](http://s6.postimg.org/hubrc320x/IMG_7686_1.jpg)
***NOTE on OZ 19" FRONT wheels. Very little clearance from the caliper if you place the wheel weights on the outer edge of the barrel.
HOWEVER, if you place the weights on the inner edge of the barrel, once you load the car and start driving, you will hear a clicking sound. That is because the brake duct is hitting the wheel weights.
***You will need to trim the front brake ducts in order to make these wheels work. Not a big deal, but be aware

Ready for next weekend.

1, is that ben in your garage? kick him out. he breaks everything.... or was it you who broke the GT3?
2, nice tire storage in ctr bay. what are those two little doors up there lead to?
3, i think i have more wheel wt clearance to caliper than your do. that said, always put wts out the very back side of the wheels so as not to interfere with anything. you want STATIC balance not ROAD FORCE.

2. Thanks. Doors lead into attic for additional storage. You access the tire shelf and the door by taking a ride up the lift. Cool, eh?

3. Yeah, I think the OZ wheels have less inner diameter clearance. What do you mean by back side of the wheels. Inner side where I have them right now? Or somewhere else?
