2017 Season-Changes

43 posts in this topic

I'll be back this year from a long absence in the Subie. Trying to decide on a tire that I can do time attack with and also autocross. Will be getting new brake pads (undecided on make), rebuild the Tarmac T2 coilovers, and general maintenance.

We will see how badly I suck at autox from being away for so long. If I can be in the top half of the time sheets, I'll be happy... haha.

Just picked up the new whip:

... I know, I know. Another one. I have to admit they are pretty fun to race!

(for those of you wondering, yes this is Murray's old car)

You made the right choice!

Details?

2002 with 200,000 km, set up for BS with a FSB, Konis, and many spare OEM wheels. Owned by Autocrossers all its life. It's been to both coasts as well as Lincoln, so it's seen more autocross than I have. It's in surprisingly good shape for its age and mileage. Unfortunately it has been winter driven, but it was in Calgary where they use less salt, and from what I've seen on the car it's in great shape considering that. It's no cream puff or showroom beauty, but that also means that I don't have to worry about it too much. The last owner put a stock muffler on it last year, which made the drive home a lot more tolerable than the last two S2k's I've driven on long road trips. No drone! :)

Congrats! 

Hope it's been good so far, so jealous of the hitch/trailer (?)

Yeah, I bought it with a trailer and 3 spare sets of wheels (two are bare, one has some old rubber still on them). Funny enough, this is now my most capable vehicle for hauling large items - I sure could've used this last year when I bought a freezer! :P

Now you can haul garbage to the dump in style! 

Looking forward to a little AP1 vs AP2 action this year!

At least Sam took one away. Think of it as you just keeping the numbers level, as no one likes change right ;)

Shall be an interesting year! 

Tire changes will be the big key player as evolving compounds and new sizes may drastically change the playing field in classes. I predict the 245/15 to have the potential to upset the top in Street Mod.

Drone is a right of passage ;)

Sounds like a good pick up, can't wait to see it in action.

Nice job Beau! 

I've hauled a washer and dryer on my S2000 trailer before. Totally awesome!

245/15 ? what brand, and what cars are you talking about upsetting Shawn :)

Going to try and limp my RE-71R's through the season, tire wear on these is pretty brutal, especially with use at Gimli. I might consider a different tire once these are pooched depending on what the reviews are like on the RS4's and Star Spec 3's.

Hey Nhil. How bad did your RE-71R's fair at Gimli? I was planning on doing the HPDE but am concerned that the 2 days on the track might kill these tires, I have ~6,000kms and 8 AutoX events on them so far.

On anther note, picked up a Koyorad with silicone hoses, data logger, ported and ceramic coated exhaust manifolds,digital tire gauge and a whole bunch of maintenance stuff. Still have a few more things to grab before the season starts.

245/40/15: https://www.tirerack.com/tires/TireSearchResults.jsp?zip-code=&width=245/&ratio=40&diameter=15&rearWidth=255/&rearRatio=40&rearDiameter=17

BFG Launched this size for the Rivals S. Note the tread compound is the same for 2017 however all tires 255 and under have an ungraded belts package, apparently this should improve the steering feel over last year's model.

Hankook just launched the RS-4, this is a brand new tire model from the old RS-3. No word yet on how they compare to the RE71's or Rival tires since they haven't landed just yet. they offer a 225/45/15 and a 245/40/15.

Maaxis Victra VR-1 also come in a 245/40/15 but they are proven to be slower than last year's 225/45/15 Rival S. Grassroots Motorsport Magazine did a test last year.

Pretty sure the Corolla could fit 245/40/15 up front. B)

Nicely done Beau! 

You S2K guys do realize if you bought a car with a trunk you wouldn't need a trailer and you just might get some torque on the side. :D

I wouldn't say they faired poorly but they will get eaten up quick. I had 5 hot lapping days (at approx. 25-30 laps per day) plus a dozen or so events with a few of those codriven plus some daily driving. The right outer sidewalls are fairly cooked especially from all the right handers. With a heavier, awd car I would expect the wear to be to be worse.

I'd estimate based on what kind of use you have on them now to be pooched by end of season, maybe earlier depending on your driving style and how they wear at autox. I don't think one HPDE event would kill them.

Dam, I really don't think I will go to a 245.... I think they would only slow me down (not enough HP)

The tires I use are already taking power away from the car.

I will buy a new set of 225/45/15's(Rival S), and I am also going to experiment with some 215's and lighter rims (less tire but less drag).  The reason for this is, my car with 185's on it is so much faster off the line and in general that it is almost unbelievable.  Now I know that I will lose some control with a narrower tire, but the speed gain could be worth it.  I was always on the rev limiter last year with Shawn's wide open big car tracks......lol.  I couldn't get more speed without going to 3rd gear, the hope will be that I will be going faster before I hit the rev limiter....?  Not sure if the math is correct (getting advice from all corners of the globe).

Please feel free to offer opinions (Joe...lol)

Thanks Tim! Actually, this car has a lot bigger trunk than my last convertible (Miata). Just because it isn't based on a truck platform (ahem, corvette), doesn't mean it can't tow!

Magne, I'm looking forward to battling it out AP1 vs AP2, but also there are a lot of other AP1s I need to worry about as well. So there should be a lot of competition. I'd like to try AP1 vs AP2 on the same course during one of the events, maybe during fun runs or TnT. I'll let you do the same of course. Let's figure out some codrives. Not only to determine which car is faster, but also to feel the difference in the cars and how they behave at the limit. The obvious power and gearing differences are well documented but the subtleties are what I'd like to really find out. Nice that you have a cable throttle car, I've heard that the electronic throttle cars (06+?) lose a bit of driveability/feel but of course that's just what I've heard.

I agree!

I'm in for some nerding-out on this. I'd like to compare data, overall weight, the thrust curves between the cars and see if our generally faster local runway courses really do favour the taller 2nd in the AP1 and if so how much. I assume you will be running 225/16 square? I have a set of 245 square ready to go. I'm also game for swapping wheels at a test and tune (not legal in Street) to see what kinda of advantage the AP2's 17" wheel & tire package has on the AP1.

Yes a narrower wheel and tire package might shave a sliver of time in straight line acceleration, on a big road course with long straights this might also be important (GRM magazine's article last year on the 245 vs 225 tire test touched on this at COTA) but in this autocross sport it's all about lateral grip. Your light Carolla on big sticky shoes has that heavy German Panzer beat in any transitional element, you want to maximize that advantage not reduce it.

Think of it this way, you have a corner you can currently take at 60km and it leads to a straight with a top speed of about 90km before the next turn where you need to brake to 60km again. What I'm saying is don't worry about that 60-90 acceleration time. Focus on increasing the grip so rather than leaving the corner at 60km you can now leave or enter the new corner at 70km. Momentum car FTW!

I wish we had the same bolt pattern, I would gladly borrow you 205/50/15 Rival S's on 15x7 wheels to compare back to back... I can almost guarantee you would not be able to match the time set on the 225 15x9 setup. Joe had 15x7's with 205 Dunlops back in the day... maybe he can chime in.
