Redline Time Attack Round 1 at Buttonwillow CW 13 on Feb 16/17 Weekend. Our plan was to stay in Street Class with Hankook RS3. There were 2 other fast s2000 drivers which already hit 1'59 will be in the same class during the event.

Saturday:
Since we took off the ABS unit completely and installed a Brake Bias valve. We were testing out the car with heat-cycled out RS3 and spending the whole day adjusting the brake bias and different brake pads. Best Time was 2.00.02, we have confident that low 1'59 or high 1'58 is very possible with a brand new set of tires.

Sunday:
Bad news - Rear brake rotors was cracked badly. We had a spare set of front rotors, but not the rear!! So we called around all the part stores in that area and finally found one that will have them available around 12:30pm. In this case, we will miss all the practice session in the morning and the first round of time attack.

Bad news #2 - We tried and read the rules carefully to make our car to stay in street class but we missed our GT-Wing. I never never noticed my wing is that big until today The wing of the car extends out of the rear bumper. Street class denied, we are bumped up to unlimited class to against some ZR1s and full prepped Race cars. I have no choice but to swap in a set of Toyo R-Compound tires instead

At the end, despite the lag of morning practice, we managed a 1'58.5 best time and secured the 2nd place finish. We still have tons of time left on the table, because the brand new tires and brake pads were not broken in, and the time attack session was only 3 laps + 3 laps only. It's very possible that we can achieve at least low 1'57 if everything is going the right direction.

At the very end, we are invited to do a super session with all the top drivers all the day. We are the only car that under 300whp in the group.

To get bumped into unlimited class and still secure second place on the Z is a big acheivement IMO. very sick. Congrats dude. Awesome driving.

Are those Nismo's you ran on the competition or Rota's?

 

What are the tire allowances in Unlimited? I don't follow the rule sets for the West Coast TT series...

I would assume non-dot is legal in those classes, right? I would run some hillclimb compound Avons...you are probably looking at a 2-3s quicker lap than the new Toyo 40 treadwear RR's. Of course, they are going to wear like crazy, and fall off after a lap or two. That said, that lap or two will be FAST.

 

Nice driving and sweet vids! And damn that Rx7 was in a very bad spot!

 

^lol. yea. he's like beckoning you to T-bone him.

BTW Pchio, is that the Qstarz you're using as laptimer? Bought one a month back but never got a chance to use it yet. How is it so far?

 

They are Nismo LMGT4 +12 offset

It's open in unlimited class. But there will be 7 rounds during this year. I dont have enough budgets to change tires every race. I am obviously not fast enough to be compete in Unlimited class. I am thinking to drop back to Modified class with 60 UTQG + tires. Maxxis RC1 seems like the best tires for this class, but I have no experience on them yet.

Yes, the rx-7 appeared much faster than you can see in the video. First session, first lap brand new tires and I had to ran off track to avoid him.


Yes, Qstarz Lap timer. Its very accurate compared to the official transponder. The color screen showing red (slower)/green (faster) helps a lot. I dont have to look at the screen and knows I am faster or slower around every sectors.

 

What model is the hill climb Avon tires?

Since it is just a 3+3 laps TT, if it does requires long warm up time, I can use it for 1 session and save it for the other round. :P

 

Very cool. Awesome car, I love that it's still street trim and yet so fast. I haven't searched, but figured I'd ask, there isn't a build thread or blog on this Z is there?

 

No build thread for it. This is the car I have building up for years with trial and error. Its been gone through the third set of different off the shelf suspension and finally I decided to go with the high end one in the coming month.

Car weight 3170lbs without me. I still have a lot to do to cut out some weight to be competitive. Everyone is telling me to give up and get a s2000 instead, but I told them no. I am just that stubborn, Z rocks! LOL

 

So am i going to see you out at Willow in a few weeks.

 

Nice job! Great to see a competitive Z in Time Attack!

 

Cool vids!
