Anybody planning on any changes this year? It'll be the first year of open boost and the 93 octane limit. Hope to see more cars (and Evos) in STU this year

Im really interested to see what we're able to get with the open boost control. Assuming the X guys will start making much more power, probably octane limited, than the IX. Whats subaru or the FoRS
going to manage?
going to manage?
as i understand it, the FoRS guys are going to pick up a ton of power. idk what the Xs are going to do, and the STis are also saying power gains are minimal to none, especially since we're all going to 93
93 is certainly going to be a limiter. Evo is good with our biggish turbos but lame with the crappy OEM boost control. I'll be curious to see what tricky stuff people come up with to get the boost moving up.
Been a while since looking at ST* classing in detail, but would the n54 and n55 motor bmws fall in STU? If so, open boost would definitely wake those cars up, too. Still mac strut front suspension and not the lightest, but might be interesting.
Looks like 135 and e9x 3 series are both in STU and IIRC they being 2wd can actually put in a real LSD.
That could actually make for a pretty rad dual purpose car or supplement to a broken SM car

I used to have an N54 135i autox car. Only competed in FS with it though. IMO they don't make great autox cars. They're pretty heavy and have tons of problems with understeer and despite pretty good steering feel it sometimes washes out on tight chains like coming out of a turn and immediately going into a chicago box.
It definitely wouldn't be as bad in a STU or SM car but mods aren't exactly cheap for them either. Neither are consumables.
But I did absolutely love that car and the N54 is a beast of an engine. I have a feeling in a few years the N54 will be kind of like the new 2JZ; holds a lot of power without needing to be built, not crazy expensive to replace (I used to see longblocks sell for under $2000), and easy to source because they shoved them in so many cars.

I've heard the 135i can't fit wide (anything past 255 or 265) front tires, so that might not be all that appealing. Genesis Coupe is also in STU (particularly the later model 2.0T), but it's also limited when it comes to how much front tire/wheel you can stuff under there. Either way, it'll be interesting to see if anyone builds those cars 
Also, maybe we might see an STU MSM show up? Not sure how open boost affects them, but I hear they're limited by stock injectors.

Yea I ran 235 front tires and it fit fine but there wasn't tons of room. 255 is the absolute limit without hacking on stock front fenders and that still means a decent pull to get them to fit.
Currently have 245/275 on the f30 335. Could definitely fit a little more as is. Wait. Gotta stop thinking about this. I already own a SM car. I should not be building anything else, even for st.
Joining the STU ranks this year with my Evo X. My car is bone stock as of now, but hoping to have it all ready by the first event for NNJR this year. (March 31) Had a local friend part his car out and was able to pick up his JRZ RS Pro's and his wheels so have a solid base to start with.
I will be starting off the year with the Nexen's. Hopefully they can handle the weight of the X. lol Depending on how the car and I perform, I will consider competing with it Nationally. Here's to a good year!
