STX Gurus lend me your eyes...
 
So I bought a modified car earlier this year. Some of the mods put me straight into CSP which has been my playground with no local competition. My e30 was in DSP before that with the same issue, and it's frustrating. I don't want to go to full street prepared prep, so I'd like to drop a few little mods to fit into the STX sandbox. Possibly give a go at nationals next year if I'm feeling frisky. Before going crazy it seems like I should get some fresh eyes on this.


Here's the mods I should be able to keep:


Whiteline Anti-Dive Caster kit

Raceseng Cascam Plates
Grimmspeed strut brace
Whiteline Adjustable end links
Eibach Anti-roll kit
KW V3 coilovers
SPC adjustable LCAs
Falken rt615k+ (for now)
Sparco Champion wheel
NRG Gen 2 quick release
NRG short hub
Forever Sharp horn button
Goodridge stainless lines
EBC Yellowstuff pads
DBA T3 rotors all around
Motul RBF600 brake fluid

Motul 300 Gear oil trans/diff fluid
OFT v1
Beastronix Speed Academy pedal dance box
Wheel studs



Iffy class stuff:


Grimmspeed master cylinder brace



From what I can tell the following put me out of class:


e85 tune

Hooker Blackheart catless front pipe + catless Tsudo UEL header/overpipe

Whiteline Roll Center / Bump Steer Kit (Ball Joints, Tie Rod Ends)
Whiteline Adjustable Toe Arms
Enkei NT03+M Wheels 18x9.5 +40MM (Black)
Velox Throttle Pedal Spacer Kit
Downforce Carbon Fiber Front Lip
Carsmo Design Rear Duckbill Trunk Spoiler
Perrin Steering Rack Lock + Whiteline Steering Rack & Pinion Mounts




Any thoughts or suggestions are much appreciated!

throttle pedal spacer kit should be allowed. it is a driver interface mod or "comfort and convenience" Hell I run a steering wheel spacer too

but yes the e85 tune and everything else would be non STX legal.

The master cylinder thing: " t was approved in August Fasttrack.

#22139 Master cylinder brace allowance in ST
The STAC and SEB recommend the following allowance for a bolt-on brake/clutch master cylinder brace mirroring the allowance present in the SP category. This is as a new line in section 14.6, as follows:
“G. A single brake master cylinder brace may be added provided it is bolt-on and serves no other purpose.”"

For locals I think you've nailed it plus the above about the cylinder brace.

nitpicky nationals level problems:
SPC LCA's have a spherical bearing that's not legal, you can press in a replacement bushing (Diftech makes one) or swap to a different LCA
Sparco steering wheel should be weighted to match OE steering wheel weight (or just swapped back to OE)

If you're winning, it's not because your steering wheel is 5 lbs lighter or your rear lca can pivot a direction it never needs to pivot so I wouldn't rush to fix these unless you're headed to Nationals with the car.

IMO, I'd switch it back to OEM. There is a rule about the airbag as well.

Quote:

13.2 D. Alternate steering wheels are allowed, provided the outside diameter is not changed by more than one inch from the standard size. Steering wheels with an integral airbag may not be changed.
Now, if you were to find a wheel that kept the OEM airbag, that could work.

Those are street class rules you listed, not street touring.



Here's the street touring rule:



Quote:

14.2 D. Any steering wheel may be used. An alternate steering wheel assembly, including all mounting hardware which replaces an airbag-equipped wheel, is not required to have an airbag but must weigh at least as much as the standard assembly. An alternate steering wheel is not required to have a horn button.

You're right. My bad. I used Ctrl+F and it moved me back up to street and I didn't realize.

Nice to know about the M/C brace.

I'll look out for a different LCA or just swap bushings if things get serious.


As for the steering wheel, I think it's pretty close in weight when I factor in a heavy metal cruise control bracket, horn button, quick release stuff, and hub. One of these days I'll weigh it all to compare, but don't think it would require much effort to get them close enough.

No worries. I've done it myself a couple times before.

Only thing I was going to ask you is did you check the weight on the steering wheel. Most aftermarket ones need ballast to be legal.

I'll have to see what I can find for ballast. I know locally I'm good, but for Mid-Div and Nationals I know it's going to be something to look into.

Last night I noticed the spoiler adhesive was already starting to pull away on the bottom side of the trunk lid. Next thing you know I've spent 15 minutes pulling and prying to get the thing free from the trunk lid. Once it was free my gut got a bit squirmy. This thing has been here a while. After some hasty cleanup, the paint doesn't match the rest of the trunk now, and there's enough blemishes/scratches that a re-spray would be the only option. I'm not a painter.



I panicked a bit. A lot really.


Some cleaning and scraping took the old adhesive stuff off. My fingers are now heavily blistered. What a genius idea this has been. I stared at it for a few minutes minus the spoiler, and then proceeded to stick it back in place with new 3m trim tape. Not a fan of the looks, but mainly because it's going to cost some money to get the trunk lid back to purty status. Maybe STX is for the birds?


I'll start looking for a whiteout trunk to swap or buy before too long. Not the outcome I was hoping for, but at least I know now.
