Installed the TRD “aero stabilizer” today.

TIL that even exists. Now I want one.

What are your wheel center to fender heights?

OMP ARS-R seat installed today. Need to make some minor adjustments but baseline setup feels nice. Used PCI seat/slider mount and a 2.2 ohm resistor from BradsHacks.com for seatbelt. All bolted up very nicely.

Also got some 255 V730s mounted on the 17x9.5 Apex VS5-RS wheels. Next track day is Buttonwillow this Saturday April 1st. Hoping to beat 86Drive Challenge street class record (I am one tenth off currently) in the morning then go sub 2 in the afternoon.

Track day at Buttonwillow yesterday. Day went pretty much exactly as I'd hope for minus the fact I lost my transponder (and apparently $500 if they can't find it) in the first session.

My plan was to do 1-2 sessions with my Champiro SX2s on to try and beat the Street class lap record in the 86Drive Challenge. I successfully completed that with a 2:01.66 and 2:01.67 in my first session. Below is the 2:01.67 lap which I liked more.

Having beat the record, I threw on the V730s for the second session to try and sub 2. On my second to last lap I finally achieved it, running 1:59.05. I was actually expecting to be able to go a bit faster, thought high 1:57 was doable, but the grip wasn't as strong as I expected. The conditions were a bit worse however as it had heated up significantly in the two hours between sessions.

My afternoon sessions were pretty relaxed, had a few 2:01s and took a friend out for a ride along. Car ran fantastic all day, although oil temps did reach 250+ a few times. I should probably throw on an oil cooler, but I am planning to take a bit of a break for the summer anyway so may hold off.

Here is the sub 2 lap. Car felt great with the V730s. The grip actually was a bit lower than I was expecting, but the sidewalls felt slightly softer and the car much less oversteer biased than with SX2s. I felt like I can drive this tire harder and it was easy to hold it at the limit through long sweepers.

I also love how these VS5-RS wheels look versus the ARC-8s. Great concavity with the width and +40 offset.

Track day at Sonoma this weekend. Have a very good day, set what I believe is the current chassis record with a 1:51.796. Car ran fantastic. Overall a very good day.
