just another sunroof-less ZHP autocross STX build and events chronicle

[GoGators]

Got 4 runs in the mid-eighty second range at FIRM. Had a lot of fun on the old tires, but wasn't competitive in class. car feels good, but has no grip braking, accelerating or turning. video has my least worst pass and my largest off course.

final event of 2016 for JAXSOLO. pretty happy with how the event went. I placed 4th in STX of 8, running about 1.5 off the winning pace. considering my considerable tire disadvantage, I am somewhat positive looking ahead to next year and new tires. assuming that I cannot find 17x9 wheels in the next month, I will be buying 255 nexen SUR4 for my 18x8.5 autox wheels. I did go ahead and adjust the rear bar to full stiff ahead of getting new tires. that resulted in being SUPER loose on the old tires.

after the competition laps of our final event, see previous post, we ran some 'fun runs'. video link is a few of my oooppps, pushing the oversteer prone (with full stiff rear bar) too hard during competition runs and then disposing of the old set of race tires during a 'fun run'...

ENJOY.

between season update. got the 255/35/18 nexens mounted up on my SSRs, they are ready to go. going to scrub them in the weekend of the first autocross which will be 5 feb. I replaced the transmission mounts, after trying ECSs poly mounts I ended up buying new BMW mounts. my old one had compressed permanently by more than 1/8". Next week I going to replace existing akebono brake pads with hawk HPS 5.0 set, flush the fluid while I am down there. I already reset the rear sway bar to full stiff and front to least stiff, so setup wise, I think I am ready for the much improved tires (ran a used set last year).

look ahead to next season. my local SCCA chapter stands to gain even more entries in STX. looks like it will be larger than any other class by a factor of 3x or 4x. favorites are, of course, AE86s and a civic si. I think an overall of third in class for 2017 would be great finish for next year.
no big planned changes for the car this year. just work on better, consistent driving.

event #1 for 2017 is in the books. came out second in STX (of 16) and 15th overall of 77. good start to the year. its my first time running at this facility (clubs second time) so between the new-to-me surface and new tires I don't think I got the most out of it. The car was definitely still loose, so I plan to go back to the less stiff setting on the rear sway bar. I have been too busy to remove the autox tires/wheels from the car, but I zip-tied shock shafts to see if I am contacting the bump stops, particularly up forward. video of my best run.

2nd event of 2017, ran at the most local road course, FIRM. placed 5th of 22 in STX. 30th of 105 raw time overall.

the new Nexen SUR4 tires finally got hot. I (as is typical) use shoulder scrub/wear to help figure tire pressures. been running low 30s, typically a touch less in the rear than front. took some pyrometer readings to see if temp were fairly even across the tread. they were mostly within in 10 deg. topping out in the 150s, after a re-run.

this event I ran both sway bars at least stiff. front felt as good as a 3250+ lb car could, rear a touch looser than I would like, but its better than understeering.
