Yes, Crows, not many digs, some sections of rev limiter and a third gear shift so the gearing helped imho, I’d be surprised if it was a significant negative anyway. I wouldn’t put much stock in stx times, my car is far from dialed, I’ve got a whole paragraph of excuses that nobody cares about lol but I did find half a second in the first fun run (and was able to repeat it) and after watching Marks video there was easily more on the table. The Civic is a shaftworks testbed, it also ran FSP this weekend, I don’t think it’s “ready” either, Adrian is a very good driver though.

Fifteenth in pax for an undeveloped car is a good sign, I have no doubt it will get faster, top fifteen is loaded with champs and trophy winners in developed cars and the CTR placed very well regardless of pedigree.

I’ll just post the videos because nobody will benefit from me tap dancing around it, they’re public for a reason.

DS 57.044

STX 57.200

Maybe with shocks and some alignment tweaks the car will be able to carve out its spot in D-Street.

Not the overdog it seems

Mark got significantly faster with a few more (fun) runs, still thinks it's a jump ball. Also, he says the CTR driver is pretty darned good.

22mm Perrin and crash bolts on mine -- just 1.5 tho. Is that fairly typical so far?

[DocWalt]

I got -1.3 with the crash bolts, sounds about right

Yeah, I'm at 1.1 and 1.6 L/R

Shifting the subframe might help even that out fyi, a good alignment place can be willing to put in the effort to do that.

That's pretty amazing for OE crash bolts. Most people are only able to get closer to -1*.

I couldn't find an alignment shop that would touch the subframe, but if it is like the 1st gen, it isn't terribly difficult at all. And a 1 or 2mm shift made a massive different in alignment numbers. The biggest challenge is physically getting the subframe to shift. Had to get creative with ratchet straps.

Just from watching you on course on Saturday, looks like it might be time for a smaller FSB? The Perrin 19mm is probably the better option.

[DocWalt]

Based on math, I'd definitely do the smaller Perrin bar for the BRZ. GR86 *maybe* needs the 22mm but I doubt it.

Not sure if Steven Hughes is on here but would love to know setup info on the Red Hills NT winner (may be Terry McIntyre's car).

And congrats -- fun to listen in on your win! A lot of great talent behind you.

I’m Terry, that’s my car. It’s 245 falkens on RPF1 with a +48 offset. 6mm spacer in front. Nothing out back. Karcepts bar. MCS 2w up front and stock rears until perch are ready on April. AEM dry filter on the intake.

Here’s our Day 1 video:

Day 2 on Stevens 43.1 the RJ45 slipped out of the RC and stoped recording everything about 15s into the run but here’s my sloppy overdrive LOL

[DocWalt]

I can't see why they wouldn't clear. At worst, buy cheap 3mm spacers.

[strat61caster]

There should be zero problems, I had 17x9+40 245/40/17 at over -2 degrees with just bolts for awhile.

Shouldn't have any issues. I've run 225/45/17 Re-71's on +53 STI wheels and they just barely cleared in the front.

Ran the A052's last year on the 2017 PP wheels which are the exact same specs as the 2022's. 3mm spacer, but had plenty of clearance with the OEM camber bolts and ~1.1*.

I have RT660's in the same 225/45/17 size sitting in my living room right now.

If you read above, you can fit 245/40/17 on a 17x7.5 +48 with a 6mm spacer (aka, +42). If you can fit that with a 245, 225 is nothing.
