Yes the kit is legal since it's just a replacement bushing and offset bushings are allowed.

You can either use camber plates or lower control arms, but not both. I'd opt for camber plates.

Thread is now sticky! With this much helpful info in here, it seemed wrong NOT to sticky it. Thanks to all who have contributed!

Just picked up a P&L header (I think) and some Motiv pipes with only 3k miles on them for relatively cheap. Don't know when they'll go on, but I'm getting closer to my mild build. Swaybars, bushings, and a few other goodies to come from stranoparts.com in March more than likely.

I'm really blown, because I just purchased one before making up my mind for this season.

I'm 99% positive an AOS or other catch can is legal, so long as it doesn't interfere with the MAF or other input/output locations. Would have to look at the rule as written and the details of the parts purchased, but in general that kind of mod is legal.

Found it. Part of the Street/Stock ruleset. For 2014, it's under 13.10:

E. The installation of water expansion tanks is allowed. The installation
of oil catch tanks is allowed provided the function of the PCV system

is not altered.

While the ST rules state you can't modify the PCV or MAF, you can add the catch can or AOS as long as it doesn't modify/replace the PCV/MAF.

So we can delete the rear cat as long as we have the 1st cat still on?

Correct. Or you can delete the primary cat (most aftermarket headers) as long as you have a secondary in stock location, as it is within 6" of the OEM primary

Ranatsu · 01-30-2014, 04:45 PM

You can delete both cats but you must have a cat within 6" of the rear most stock location.

How about perrin mounts i have the read shifter bushing and the trans mount

Kido1986 · 02-03-2014, 08:08 AM

All bushings are fine, as long as they contain actual material and not solid mounts (aka Aluminum)

So... What is everyone thinking on tires since the RS3 seems to not be able to be found. R1R/ZII/Rival

FastWhite · 02-03-2014, 03:06 PM

R1R's are only good for this year. 140 tread wear.
ZII's apparently will fit the stock rim In a 235/40/17.
Chime in if that is a no no.
As that is what I was going for on my next set of tires.
My current Rival's are holding up well and are a blast.
But change is good right.
