This is my first track video with the new to me Drift HD170 camera. This was a new personal best of 2:34.8 and still only good enough for third in class but that was behind a couple of really talented friends that I have no problem losing to. This is the first wide angle camera I've run and the first time I've had good footage of the inside of the car. One thing that really struck me was the amount of flex my Corbeau FX1 Pro goes through. Keep any eye on the right winglet in the turns! (IMG:http://www.frrax.com/rrforum/style_emoticons/default/blink.gif) I picked up an I/O Port seat brace and will be installing it before the next event.

What's the the steering wheel being so out of whack?

Lines look good, I see two things that really stick out to me. Take this fwiw, ymmv, etc, etc, etc.

1. Doesn't sound like you are doing any rev matching on the downshifts. I heard more than once where it snicked the rear tires on you/brake hopped into the hairpin. If you need to work the pedals so you can heel/toe better, then do it. Also if you need pads with more bite to help you feel more confident, well we can do that too. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/smile.gif)

2. Could be more aggressive on the power on way out of a lot of corners. Not a lot of tire on the limit noise, never really working the car to keep it line. There is more there I think and that of course equates to more straight line speed.

Other than those thing looks good. Car is behaving as I'd expect with the stuff under there, you're putting it in the right places.

I put new outer tie rods on it & had it aligned before the event and honestly hadn't noticed how hosed the wheel positioning is. I know the guy that does my alignments very well and will have him correct it.

I'm still not blipping the throttle on downshifts and yes it's obvious that I need to. Watch what happens at the 3:49 mark in the video as I'm going for second gear coming into turn 10. I've exploded two clutch disks so far so that's the weak link for me not rev matching. Braking is just a confidence thing and I'm working on going a little deeper each weekend. The pads are still more capable than the driver.

I watch the video and agree about getting back on the power but it sure doesn't feel that way when I'm driving it. I'll work on it. In that video I've stepped back to a 275 section width tire from the Continental race series and they just don't seem to make any where near the noise of my 315 width Hoosier R6's. I've also gone to an 18" wheel and the shorter sidewall is taking some getting used to, especially under braking.

I had a mutual friend, Ian Stewart, tell me he thought my car would be faster on a smaller tire because I don't have the horsepower to overcome the mass of the 315's and he was right. Ian wants to drive my car and I need to let him but I would hate to see how much faster he would be than me. I've already seen how fast you and Danny Popp can be in my car compared to me so I'm well aware of the potential that I haven't achieved yet.

Here's an interesting picture from that weekend of me coming into the hairpin too hot and standing it on its nose as I turn in. Not the fast way for sure.

C'mon Jeff, you're going about this all backwards... you don't go with a smaller tire, you add POWA! I don't remember the exact quote... something about you only have too much power if you're spinning the tires in top gear at the end of the longest straight? I bet I heard that from George (IMG:http://www.frrax.com/rrforum/style_emoticons/default/biggrin.gif)

Ian actually suggested that I step back to a 255/35-18 Hoosier R6 which would give me enough points to put heads and a cam in the car and still remain in TTC. I do not have the required big shiney brass ones to drive the car like that so it won't be happening any time soon. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/blink.gif) If you want to volunteer your car I'd be willing to give it a try though.
