I was unable to get the racekeeper system for nationals, I used my codrivers gopro HD. I ended up 4th overall...0.4 out of 1st...

The batteries died on day one, so my fastest run wasn't recorded.

Stock 2009 cobalt with muffler delete and 245/35-18 kumho v710's on stock wheels.

 

awesome stuff man!!! I cant wait to make it next year Just working on getting the car prepped and getting used to it the rest of this season and tuning next

 

Do those tires rub at all? And good work

 

Woooo got a little tail wag at the :56 mark on the second vid, brought it back together nicely though. Its like you can tell when the turbo spools, car really accelerates hard to the next braking point. You obviously aren't a first timer on these courses. .4 secs is a lot of time, what car posted the best/1st?

 

a mini cooper S, I know they guy, he runs with me at miller park.

 

the tires do not rub at all.

I did get a little loose in that section on the 2nd video. Every run it was loose there.....i'm blaming that section on my .4 That was just driver error....LOL.

John is a really nice guy, I was talking to him before the event and I told him I didn't care who won...as long as we can knock the ITR's out of the top spots Only 2 in the top 5....I think we are on our way....

 

yeah there is no reason a 10 year old car should still be on top of a stock class lol.

 

If you get the chance to drive an ITR, take it. The handling is phenomenal, and it's a good bit lighter than the Cobalt SS/TC.

ex-ITR owner, but mine was a Honda Challenge car.

 

I would love to drive a ITR....I got offered a drive at peru this year but wasn't able to make the trip. I put mine on the scales this year with 1/8 of a tank (little wing/no sunroof car) and weighed in at 2828 without me in it. I was talking to the ITR owners and most are in the 25xx range. That weight paired with 275's out front is a deadly combo

 

nice runs, i heard nationals was awesome

 

i have raced both on street tires tho. The ITR was amazing, the mini s... was fun but felt slower. I like the cobalt a bit just cause it has underdog status Plus I like the idea of developing a car.

 

Yeah last year I went to nationals in a mini cooper S and this year I did a pro solo in one. acceleration is for sure lacking....but man it slaloms and stops....

Anychance anyone will make it to the tri-state national tour in Oct in Blytheville, AR?

 

i dont think i can make it

 

What are you tire pressurs at on the V710?

 

45 front 50 rear

 

So do you guys mostly trailor the car to events in other states or what? cause this is my one and only car at the moment lol..

 

Nope...I load everything up in the car and drive it. It's a stock car

 

I was looking into a hitch and small trailer to tow with the cobalt but ill save the extra pounds the hitch adds and just load everything inside.

 

Are you guys running Konis? I like the stock ones, but I think there's room for improvement. I've been in touch with Lee Grimes @ Koni, and he's willing to dyno stock v Koni if I can find some fronts to send him.

 

I have only rears right now. Testing them out at different settings right now. from the looks they are about the same compression as the stock ones but you can play around with rebound and maybe get the car to rotate more (again just rears)

The stock front ones are solid i gota say, plus i dont feel like cutting out the stock ones to put konis in just yet. I had to do that on my old civic and nothing but nasty clunks up front.

 

I'm running the stock shocks. The car rotates just fine for me....it's actually pretty loose. If I do, do shocks for next season then I'm going to get a set of double's. Probably some koni da's or see if ast can do anything. Both the other cobalts at nationals had koni's and 255 Hoosiers...

 

holly 255s!!

yeah i think the person who can get the right combo will take the cobalt to 1st place at nationals. This is where it gets fun, whos doing what how they are doing, what can you do different to be better.... **** i love racing

 

Thats the thing...the car has it in it stock. Like someone said earlier, around 56sec mark on day 2 the rear end got real loose and that was my fastest day two run. That was in a real fast section. There was more then .4 in just that section and through the sweeper that I lost by not hitting that right.

I have ran the 255's earlier this year and I like them, but they only last about 25-30 runs before you cord the outside edges. The 245's are a shorter tire so steering feels more nimble, thats why I run the smaller tire. I only run the kumho's because I can get more life out of them. Initally the hoosiers are more grippy but you will be buying them every other event

 

uh. You guys are killing me with all this talk of nationals!

 

Wow.. good job David!!!!
And you did with stock shocks!!
The Mini S' and ITRs got many more years of developement under their belt.

Were you running stock front bar as well?

D stock is looking to be a really fun class... Good tight competition between ITR, MiniS and ITRs...
