Default 1st time on the track since TIC SST install *with video*

I had my 2003 WRX on the track for the first time since having my TIC SST's installed this past Saturday at Nashville Superspeedway for an HPDE. All I can say is holy cow! I am back in love with my subie. It will actually turn in now and has a very neutral balance. I was experiencing some overheating after about 10 minutes on the track, so I would almost idle down the front straight to get the engine to cool down. Once I got back into the turns I was dumbfounded by how much distance I would make up on the people in front of me. My subaru actually likes to turn now!

I followed the weekend up racing in SCCA in the XP class. There were only two of us. The other guy has been to nationals in his vette. He beat me by less than .03 seconds, and I know I could have made that up in a few parts of the course. Out of 80 competitors I came in 15th place and half of the people that beat me were in open wheeled cars. I was the fastest of 5 or 6 other Subarus out there, most of which were STis.

NSS, you say...? That's just a few hours from me.

Glad you liked the track and awesome videos!

I'm curious why XP for AX, though...? And who was the group you ran at NSS with...?

Xp because I have alk and fender braces. I ran with bmwcca, but I want to do a NASA event before the year is over.

Hi ted dibiase,
Name familiar to me. Were you in wrestling before! Kidding.
It was fun watching you driving. You need a little more practice.

Thanks for the advice, Cherlie. Currently I'm looking for sponsors. You can get in on the ground level of this investment. I just need about $5,000 to register for more events this year and to pay for rotors/pads/gas/lodging/track prep/etc. I have a paypal account set up let me know if you are interested in investing.

If the investment opportunity doesn't peak your interest, I would happily wager 1 crisp dollar bill against you at the next kyscca auto-x event.

Gotcha. I figured it was the ALK that bumped you that far ahead class-wise.

nationals are in Nashville this year. I doubt that I will qualify, but do plan on attending at least one day of the events.

I missed out on going to the ATL Tour, I'm hoping Nashville won't conflict with another trip I'm planning.

Things that will bump you to XP or OP
ALK
Botox bolts
Engine mounts + Pitch mount + fender cowls

The first time I went to an scca ax, this is how checkin went.

Reg worker: What class is your car?

Me: OP

Reg worker: {rolls eyes, unamused} I'm putting you in STO.

engine mounts and pitch mount don't bump you unless they're made of solid metal.

What's your alignment specs? What sways? What damper settings? I'd expect a little less understeer.

I've had a very similar setup to the SST coilovers using D-Specs and GC coilover kit that I've had and enjoyed for a couple years. TiC did their math and build something that works very well. It's daffy how good a setup you can get when you don't try to fight physics or play stupid games. Use the right springs, right damping, and give yourself plenty of travel and the car will drive beautifully and will do so with ease.

A note on damping when just plugging dyno numbers, you should be in the neighborhood of 7-8 from firm on the front and 8-9 from firm in the rear when running the stock spring rates. Any firmer and rebound will get too high (>100%) and cause traction issues over bumps. The softer you go, the more chassis bounce you will get. TiC even says their favorite setting is 7 front and 9 rear. The slightly softer setting in the rear is good for those who like a tossable car and something I do on occasion as well.

I'd toy with camber settings to optimize the tires if you haven't already done so. Temp gauges aren't hard to get and not too pricey. I'd also look at sway bars and toy with sizing to get the handling balance you want. The springs alone with no sways is neutral. Add sways and you'll get whatever you make from it. I believe on a wrx, you are around 2mm bigger in the rear to create the same effective spring force at the tire both front and rear. You can break out the tape measure and plug in the geometry into a sway bar rate calculator to get a good estimate of spring force. Since the coilovers are geared for neutral, to maintain neutral you need the sways even too. You can of course add or subtract as needed for a little oversteer/understeer if you want.

Cant have fender cowls in Street Mod, and you cant have engine mounts + pitch mount in Street Prepared.

That pretty much only leaves XP and OP. I read the the SCCA Solo rule book a half dozen times, and that was my take.

You certainly can have engine and tranny mounts in SP. As long as they don't have more metal content than stock. The group N mounts for example, which use stiffer poly are legal. Re-read the rules. Not sure but they may even be legal in ST.

Group N mounts are rubber, just to be clear.

OK. I know my posts can be long winded some times, but you guys are phoning it in today.

I said:

Engine Mounts + Fender Cowls + Pitch Mount.

From section 15.10 the SCCA 2011 Solo rule book:

J. Engine mounts may be replaced, but must attach in the factory
location(s) without additional modification or changes. Engine position
may not be changed. Hydraulic shock type rear engine locators,
or bobble struts, may be replaced by manufacturer’s performance
part or aftermarket replacement part. This part must retain factory
dimensions and attachment points, including factory design. (Example:
If factory locator/bobble strut is gas or hydraulic piston type,
replacement part must be gas or hydraulic piston type.) If one or
more non-OE engine mounts are used, 15.10.K does not apply and
a torque suppression device may not be used.
K. One bolt-on torque suppression device may be used. A torque suppression
device attaches from the engine to the body, frame, or subframe
in one location, and controls engine movement at that location
along a single axis only. It may serve no other purpose.
Examples of permitted devices:
1) a chain
2) a rod with spherical bearings at each end.
Examples of devices not permitted:
1) any link which confines movement along more than one axis.
2) an engine mounting plate, or one or more plates rigidly bolted
between the engine and the frame. Holes may be drilled to
mount a torque suppression device. The installation may not
include the welding of any plate(s) to the bodywork or to the
motor mount(s), nor may it include multiple non-parallel links.
If a torque suppression device is used, 15.10.J does not apply and
replacement engine mounts may not be used.
