69 Malibu Pro Touring build

Can you drift with it or is the traction really that good?

It will drift on command, and pretty easy to control a slide too... It's really predictable. Fastest way around the course is both ends slipping about equal but I do get a little extra rotation with the throttle pretty often.

I don't often hang the back way out there though, overheats the tires really quick.
 
On Father's Day I decided to hit another little local autocross, and talked my wife into driving as well. We ended our day early with a tire puncture on the right-front. I didn't want to de-bead the tire, or wear out the battery on my portable compressor (that I needed to use a couple times on the way home), so we called it quits after our morning runs.

After 118 runs and 1250 street miles on Yokohama A052s (the last 8 being 2-driver 95deg day and forgot my sprayer) the rear tires started to delaminate... this was to be my last event on these tires anyway.

Last night I mounted up new 275/35 Nankang CR-S, as the 295/35 Yoks are unavailable until late summer/fall.
I was planning to buy 2 sets of tires this year, but supply chain screwed up that plan.

I ran on Sunday with Minnesota Autosports Club, and of 137 drivers, I finished 4th in PAX and 7th RAW time.

Here's a few videos from the event.

Just touching the 7200rpm rev limiter at 75mph in 2nd gear

Got a little sloppy threading the needle through here.

hit 1 cone on this run, camera on Left side so I can review car placement in the slaloms and see where I can run tighter.
 
And some good pictures from the event

Compressed and sideways... love this picture, but wish the whole car was in it!
 
Did you have the highest-finishing large car ? I bet you impressed the others driving a Chevelle !
Is that your oldest son riding shotgun ?

There was one heavier car that beat me in raw time, a Tesla driven by Jeremy Swenson - not sure if he's considered a pro or not, but he wins a lot.
He has won overall at King of the Mountain, has won Gridlife Touring Cup Championship, etc... and the Tesla despite being very heavy, are very quick with all the EV torque, and very sophisitcated traction-control that lets them put power down very well. The car is owned by Viking shocks, and they're supplying the car for him to run at KOTM. They also sponsor his GLTC Corvette.

There were only 2 V8 cars in the top-10. Me, and an LS swapped '03 Nissan 350Z. I was about 0.8 sec ahead of him.
The next V8 car was the Viking Shocks '69 Camaro in 36th, about 4 seconds behind, driven by the owner of the company.
I had 4+ seconds on all the rest of the CAM classes, including all the newer muscle and Corvettes.

The Chevelle gets a ton of attention at stuff like this... especially since I started cracking into the top-10.
Occasionally some other old cars and pro-touring type stuff comes out, but they're usually pretty slow.

No, I'm an instructor with the club, so a lot of the other V8 RWD guys ask for rides.
I had 4 other competitors ride with me at that event.
 
I think EV's have too much advantage to compete against pure gas cars.
Maybe when more are competing they will have a seperate class just for EV.

There are 49 classes in autocross, including an EV class.

When I say "RAW time" I mean overall everyone there actual time on the clock... I was 7th fastest of 137

"PAX" is a conversion factor applied to all classes to theoretically make all classes equal based on what the top car in the class should be able to run. A-Mod is the fastest class, basically go-karts with sport-bike engines and crazy aero wings. Their factor is 1.00. CAM-T that I run in has a factor of 0.816, so in theory if an A-mod car runs a 60-sec lap, and I run 73.529 (x 0.816) we have equal 60-second PAX finish. I finished 4th in PAX overall of 137.

PAX is how they score the overall season points for Driver of the Year trophies... I'm averaging in the top-10, but will not make enough events (5 of 10, need 6 to trophy) to win anything. That was one of my goals for the year (DOTY top-10) but had one too many conflicts in my schedule this season. They also have "Pro" class scored on PAX in my local club that I will probably run in next season to battle with the best in the club rather than crushing everyone in CAMT each event. :)
 
I could watch that car all day.

How did you like the Nang's compared to other tires? I've thought about giving them a try after these Pirelli's.

Speaking of times and the Viking car, have you been approached by anyone for a Sponsorship? I would think that besting the sponsor cars, you'd get someone wanting to put a name on it.

I know some that are sponsored in other sports just by starting a YouTube channel and posting their preps, event, then post thoughts. Rack up the viewership. Then go to a company and direct them to you page with so many views.
 
Nankang CR-S is a really good tire, especially for heavy cars. More crisp feeling than the Yokohama A052 with better turn-in, but they break-away quicker so any over-driving is slower. 2nd run is the best on them, they like just a little heat in them. The Yokohama put power down better and were fastest on the first run, and needed to be sprayed with water after each run to keep from getting greasy on the next one.

Sponsorship comes with obligations, and I kind of like to be free to do things my way and on my schedule, and keep this car looking clean without a lot of stickers... when I start to prep my Corvette, I'll probably reach out to a few contacts and see if they have any interest.
 
Very nice job racing and building that car. Looks pretty sharp and the way it handles, any factory car wouldn't take that.
 
I was hoping that I could get this finished up before UMI's King of the Mountain, but decided to delete the license plate recess, so that added enough work that it doesn't look like I'll be done before then. The fancy "chrome" paint needs to go on a base finish that has fully cured for a week, so I am already running out of time for that. Steel bumpers will go back on for KOTM, but the fiberglass ones should be completed before SCCA Nationals.

Factory bumpers are 21lbs each, and the fiberglass are 6lbs each, so I am only taking 30 lbs off the car, but at the extreme ends, reducing the polar-moment.

I'm trying some "chrome" paint, which I have never used before, and hoping both the finish and the bumpers themselves hold up to running over cones... adding a splitter would help protect the front bumper though.

The rear bumper fit really well, front was not very good. Both have big seams where the molds came together that required body work.

I cut out the recessed area for the license plate, used foil tape as a backer, and put the first layer of fiberglass on from the back side.

Decent performance street tire, but not a competitive autocross tire.
I put them on my brother-in-law's '78 Firebird Formula. They last a lot longer than the sticky gumball tires I'm used to running. :)

They're good tires for high-performance daily-driver.
