They want to sell you stuff first and foremost.

Rear differential bushing inserts are legal, correct?

What are the opinions on the Whiteline Anti-Dive Kit? Is it a worthwhile bushing for an STX setup? The extra caster would be nice but I'm not sure if it's worth the money.

In what way are the SPC toe arms legal? Sept. Fastrack clarified the toe arms as follows (Note 2008 WRX suspension is same as ours in general construction)

#13859 Toe Link Clarification
In regards to the 2008 Impreza WRX rear suspension the STAC considers the rear lower arm to be a control arm and
the front lower arm to be a toe link.

Combine that with the rulebook which states:

14.8.H.1: ...Non-integral longitudinal arms that primarily control
fore/aft wheel movement (e.g., trailing arm(s) or link(s) of a multilink suspension) may not be replaced, changed, or modified.

I had Whitelines, which were very nice. I recently got a set of RSRs to replace them. The RSRs are steel Vs Whitelines aluminum. They both weigh the same amount, and have similar adjustment capabilities, but the RSRs camber adjustment position is much better IMO as it is far enough away from the subframe mount that you can actually get tools onto it easy, unlike the Whiteline part.

Honestly did not look up the rules on the toe arms as they have the same joints and all as the stock. The reason I went to them was I bent the LCA and the toe arm on one side of the car. I got a deal on the Toe arms, figured they would work as long as they didn't have spherical joints. Looks like I will be shopping around for a used OEM toe arm to stay in STX.

Yeah, unfortunately, it's one of those situations where the manufacturer considers it part of the control arm, and the SCCA disagrees.

Anybody heading to Dixie? Might be picking up a codrive in a competive BRZ if someone else backs out. If not, I'm highly considering putting all the parts on mine next weekend and driving it down the following weekend. Not sure if I'm feeling that crazy or not. Finally picked up an exhaust and brake pads from Stranoparts (Thanks Sam!) which should be here this week. Probably should schedule a tune and alignment soon if I plan on doing this all at once.

So I have a midpipe that I picked up a while ago. I know Annie's car last year didn't have one and I know it makes things louder. Thinking of leaving it off for now and then maybe selling it or putting it on later. Thoughts from this crowd?

Nothing like using a National Tour 14 hours away to do initial testing of a one week old setup. :p

See you there . We are driving from wilmington nc on Friday around noon.

In today's SCCA Fastrack the 2015 Subaru WRX is now moved to STX. I think that car could have a chance to be the class dominator. It has a similar but better advantage in hp to weight ratio, about 12 #/hp vs the FRs/BRZ 14#/hp and all-wheel drive. Has anyone run against a well prepared '15 WRX yet? Any thoughts?

[vroom4]

Haven't run against a well prepped DS let alone STX. It's been in STx all season, not sure what the fast track is mwntioning

[conedodging]

The 2015 was always classed in STX, they just messed up when making the rulebook drafts.

[tahdizzle]

There is a 15 WRX that runs at my locals, but he's not in STX trim (yet).
