MCA Traction Mod
 

Who has the MCA Tractoin Mod? Do you think it help and how/where on track? Would you buy again or is it just a "meh" improvement.

I have it and it works as described and recommend it. Better traction coming out of corners.

Just make sure to check the classing rules for whatever groups you compete with (this part ruins SCCA classing for autox and puts you into the Prepared or Modified classes).

E85 is life, so my STX car is already not STX ahaha.

"reduce anti-squat". So if I installed the whiteline rear subframe bushings to reduce squat, this is going to induce it all over again?

Anti-squat relates to suspension geometry, the WL rear subframe bushings reduce bushing play/squishiness. So they're affecting different things.

I also have the MCA part installed on my BRZ and I can say it appears to improve corner exit traction quite a bit. I do not have any supporting data though.

I have it, good mod.

Heaven forbid you attach an oil cooler to the car. instant street prepared

Oil Coolers are allowed in STX, the got added recently.

SCCA also is now allowing regions to make the call on aesthetic mods in street touring at local events(non national/pro solo type). For instance vents, lips, side skirts, wings etc can be allowed at regions discretion.


My region has lots of cars show up that are in prepared classes for worthless mods that bring them to *SP or *P classes, especially when they show up on blow suspension and 400tw tires. It isn't good for the sport as people who know nothing about autox that want to try get scared due to the class they get put in.

It's not even that people get "scared", it's just that it's not fun to go as a newbie and compete against somebody who's previously won a national title, just because you took the backseat out of your car and replaced it with $40 in chloroplast from Home Depot. Sure, it cut ~30 pounds off the car, but it's not going to make a newbie into Randy Pobst, so why be so anal about it? That's basically what happened to me, I went to one AutoX event and realized I'd spent all day to get a total of ~10 minutes driving, while classed against people who'd been doing AutoX for years or decades. I got put directly into Modified thanks to removing my back seat and also since my oil cooler is built into the radiator (Jackson Racing Dual Rad). My car was on stock suspension, stock alignment, stock power, on 300tw tires, but yep, I'm in Modified.

I guess, radiators are not an allowed ST mod, so I can see they bumping for that. I personally would have just put you in STX since thats where the car belongs.

Radiators were allowed in ST beginning of 2017, the current rules also would allow the dual radiator as long as it wasn't installed to make room for a intake...

I'm with one of the teams down in the Socal area and our president is worried about that outcome. if we average less than 100 people per practice session we are losing money. I had offered leniency on the modification gambit because even in like fwd STS, if you dont have a EF hatch you won't be competitive. and forget about CS and BSP...

Now Im a "young" hotshoe who's played in and out of Autox and time attack and even rallyx for the past 6 years, (pending status in conus) And I understand rules and whatnot. But I also know that there are exceptions for everything.... everything

good to know that local regions are loosening up on oddball rules. Something like an oil cooler or baffled oil pan isnt a cheat mod for the tight track. More or less


On the radiator thing as well as swinging WAY far away from the OP topic

"Engine cooling radiators may be replaced with alternate parts subject to the following restrictions:
1.Radiator core dimensions (width, height, thickness) cannot be smaller than the standard part.
2.Radiator must mount to OE radiator mounts.
3. Fluid capacity and dry weight of the radiator must be no less than that of the standard part. Installation of an alternate radiator may serve no other purpose (e.g., to allow a cold air intake passage)."

non standard radiators are allowed in street touring (STX for us)
I would even argue your radiator serves the same purpose as an oil cooler which is allowed
