^^Was there something on the track? Did you hit the brakes or something? Trying to figure out how it started out as understeer and went immediately to snap oversteer without much steering input.

ChrisSlicks · 12-03-2009, 07:18 PM

Not to hijack Travis's journal here but that was oversteer all the way, he just didn't catch the warning signs early enough. Certainly could have been some oil on the track or something else that initiated it though.

I really hate guardrails

It was overstear, and it was also my first time out. Definitely a noob mistake, for sure. Entered too hot, realized it too late.

I learned to manage situations like this by doing a bunch of autocross events... great way to learn car control and gives you a lot better feel and reaction instincts when back on a road course at higher speeds... if you haven't already, suggest you try it!

Just getting it out to the track this year was a scramble really, and the local Auto-x happens Saturdays...I work almost every Saturday right now

When the situation presents itself, I FULLY intend to go, however.

We have a fantastic auto-x site up here in northern MA. The course designers often set up some challenging mid-high speed elements of slaloms and sweepers and high speed corners. Typical course size is 1.5 miles and takes over 2 minutes to complete, and by the end of it you are breathing hard. I thought I knew what I was doing before, and I kind of did, but after 3 years of auto-x I can make the back end hang out at the precise angle I want and catch any slide. In the last 2 years I only spun once, and it was in heavy rain, despite being one of the faster cars out there.

I fully agree, Chris. I think the only thing autocross doesn't prep you for on a road course is when you get loose at 100+ mph... at those speeds, aerodynamic effects can be just as much in play as tire and momentum angles.

This reminds me that I need to get my ars back into autocross! It's been a year or so...

Bluemeanie · 12-04-2009, 07:09 PM

Hey Travis, I just read your post that you're going to use Robi's splitter. Cool! I can't wait to read your impressions, hope you like it.

We picked up our Rotrex SC and we'll start that phase of the project soon. The holidays will slow things down a bit but in Jan or Feb we'll have that thing spinning... Oh yeah!

Post some pics as soon as you get 'em

You get that gremlin figured out yet?

True, we max out at about 70 mph, occasionally 80 on our course. It teaches you to have fast hands and reactions, drive by the seat of your pants style. When you get to the track you have to unlearn the fast steering inputs and aggressive throttle inputs but first time track drivers that have auto-x experience almost always do better their first time out because they are comfortable with their vehicle.

I love both auto-x and track but for different reasons. Both ultimately make you a better driver.

Good call - I may take that advice too. I've put 4 track days on the car so far, but I think some low(er) speed car control is in order.

On weight - I don't think they have an alum. oil pan for the car yet, but you could always go billet ;-)

Mike · 12-04-2009, 09:33 AM

if its like the oil pan on the VQ-35, and I think it is, its just pretty much a flat steel plate. You might save a couple ounces, but nothing more.

travisjb · 12-04-2009, 09:43 PM

On a separate note, a new vendor from this forum that has decided to become an official part of my build... I will share details over the next few days... very excited about it! More later.

Travis are going to put any aero package stuff on your Z besides that plastic front splitter??

travisjb · 12-05-2009, 12:53 PM

only functional aero (splitter, rear wing... maybe rear diffuser if the right one is made), not engine mods for now
