Good to hear Tim. It looks like you got best case scenario from the damage that could be seen track side.

I'm glad it didnt take everything out and hopefully you'll be good to go shortly! I'm almost done with my drivetrain swap (5-speed exploded as anticipated) and I cant wait to get the car back out, hopefully for one event before the season is over.

Hey, congratz to Mike winning this year Canadian Autoslalom Championship. It was a great event with a very nice course on both days. 146 competitor. 4 runs per day (2 in the morning and 2 in the afternoon) formula. 4 SM Subaru in the top 5 overall PAX


Mike got 1 sec on me on the first day and was 0.7s ahead in overall PAX. It was also very close for 2,3 and 4 in SM on that day. I was able to get back on Sunday by beating him by 0.5s, I was also the fastest on the overall on Sunday, but that wasn't enough to get back the victory. Overall ended up 2nd in SM and overall. Was a very challenging week-end and a fast learning curve on using the new 315 A7. I had to get the car to almost stock height to make them fit (no time to cut fenders).

Saturday run: https://www.youtube.com/watch?v=ui2mAOEsca8

Sunday run: https://www.youtube.com/watch?v=u1euTH2hvJs

If you want to give any advice on the setup and the driving, bring them on!

Looks like a good battle and a fun course! Get some Hoosier contingency up there and you'll get the US contingent to show up Although Mike has been telling me that I need to show up for fun as well.

You're close to the cones for the most part, but there are sections where you go too deep on a braking zone and really have to park it. There's also a few places where you're really lifting off in transitions that seem like they could be done while on throttle. Basically, more aggressive in transitions, but slightly earlier braking. The 315's will give you a lot in transitions and you just have to know it's going to be there. They don't give too much more in braking though so it can be a bit confusing.

Canadian SM Rules similar to SCCA? Think the 2015 rack mod and associated cutting that was needed would be legal for SCCA SM?

Yes and yes. The front subframes are open in SM now as long as they maintain suspension pickup points and weight.

Speaking for the 02-04 WRX subframe, the cutting was a matter of a few grams, well under the 1lb rule. It's more clearancing than cutting, really.

Wish the sub frames were open as an item to drop weight. Not exactly sure how i'm going to loose this last 50lbs or so. In a class with minimum weights I don't get the restriction.

I'd love to dump the U brace for one of the many options available. I've been eyeballing the TSS fab front subframe with splined front swaybar built in, he claims with the front bar as a part of it its nearly the same as stock weight.

The original thought was by making it the same as stock weight but allowing modifications we were keeping custom subframes to only those who needed it for an engine swap. If we opened front subframes it'd immediately become a must have since it's usually a lot of weight right off the front. And it would make checking front geometry much more difficult in general.

I wouldn't mind spending some time making one and saving weight (titanium front subframe anyone?) but for most it'd just be another $1000 or so that could be spent elsewhere.

I guess in terms of the geometry issue and keeping everyone honest I can understand. I'm just getting to the point where to loose this last bit of weight its going to take some serious effort and creativity.

On a different note what material did you use for your front splitters air dam? It looked quality. My garden liner is getting tired. I tried some aluminum flashing but that lasted even less time.

Not sure if you've already done it but I'd imagine you could shave a decent amount of weight going to a smaller fuel cell.

Does there need to be a bulkhead at the trunk passthrough if I remove the rear seats? I can't remember if that was specifically required or not.

Wasn't there a provision this year that the "passenger compartment" moved to the back of the front seats if the rear seats were removed? I ask because I would like to install my battery and Accusump as close to the middle of the car as possible I think, just to keep their weight low.

Any suggestions?

Creativity is the name of the game I bet if I looked at your car closely I could find lots of weight to lose. Might not be super cheap or easy, but I know the GD's can get down under 2,900 if Devin did it.

I use Alumalite for my splitter and some aluminum U channel on the front to distribute cone impacts so it doesn't bend. Then some very thin aluminum for the air dam itself. I think it was like .019 or something for thickness. Enough to work, but still very light.

Lots of complications and cost there for weight off the wrong end of the car IMO.

Since the fuel tank is under the car you don't need a bulkhead, but you can't remove things that aren't associated with the rear seat. I left my plastic piece there because it's associated with the trunk and not the back seats in the parts catalog.

The passenger compartment is the back of the front seats if you remove the rear seats. Just don't put the battery somewhere that you're going to be breathing the fumes it puts off while charging and make sure to box it up well. Mine's in the trunk in a marine box.

I think I will just stick the battery in the trunk for weight distribution then. It's a Shorai Lithium battery, no fumes. I suppose I could run the Accusump back there too but that's a lot of extra high pressure line, and oil, to run. Maybe I will try and find a place in the engine compartment for the Accusump.

Good deal on the bulkhead, I can surely leave that plastic piece there if I need to.

Yup, having done a fuel cell once, it's not an easy job. Though it's off the wrong end, it's still lighter... and, without going over someone's car with a magnifying glass, it's an easier suggestion than shaving ounces/single pounds here and there.

Ounces make pounds and pounds make pain. There's tons of little things I've done to my car to save weight that makes it lighter, easier to work on, and more simple in general. when I looked at Ross's car that I'm driving at Nats now I pulled a good 6 lbs off the nose in 10 minutes just looking at stuff. I'll have 100 lbs out of it before the big show with some elbow grease mixed in.

You have to look at stuff in a "do I need this bracket" or "does this need to remain here or can I remove it, and can I cut some out while I'm here".

Exactly. I always have a Fein tool and a 4" grinder around when I'm working for this very reason. Don't need that welded on bolt anymore? Remove it!

Getting a GD to min weight is a lot of work but possible. My original goal was to try hitting the 2770lbs mark on my GD and run 275 to save money on tire. But getting under 2900 legally is getting very hard and expensive and that was with no splitter and rear wings. It's relatively easy to remove weight in the back, but that's not where you want to do it. I actually had to put weight back on the car to run my new 315 setup.

You can go over the AnorexicSTI thread for ideas, but lots of stuff he does is not legal in SM.

I fired it up and it idled ok for about 30 seconds, then started to miss. Did another leak down and cylinder 3 was at 90%. So the first test was a fluke. I decided to punt since I was going to be pulling the trans right after nats anyway. It's kind of odd, but now there's no real pressure on me to win or anything. I drove Ross's car at a local and it was 2.5-3 seconds slower than where I've been all year. I can get back about 1.5 seconds of that by showing him some tricks, but not all of it unfortunately.

Either way, trasharita will still be there.

Well that sucks. OTH, it means you can go just have fun.

Unfortunately I won't be there. RL has been taking its steel toes to me this year.


Cosmic irony, I still have Nats week as my vacation. So I will probably sitting at the house listening.
