Anyone have reviews on stiffener options? I couldn't find any recent threads on them. I have a Moroso oil pan so Sector 111's "subSTIFFY2" is not an attractive option to me. I would like to hear any reports about Sec111's "Seriously Lotus Subframe Stiffener" or any other similar products.

Why do you want to stiffen it.

I had Lotus Shear Panel before, did not feel any different.

May be I have a hard butt.


Currently I have S111 subSTIFFY, feel the different right the way. But this parts is damn heavy.

Because my last track day I was having a hard time keeping up with an older guy driving a Chevy Cobalt. His only mod was a mega-huge sway bar so I have to find something to fix on my car or admit that he's a better driver.

Why is it so hard to admit he's a better driver. There's no shame or harm in it in my opinion. It would just drive me to be better.

It has been said a million times, the best mod you ca buy for your car is driver training.

You're right. Admitting isn't the hard part- accepting is. I want driver training PLUS all beneficial mods! Not to mention that thinking about the gear and car set up is part of the fun.

I'm looking at the Seriously Lotus part myself. It seems adequate and actually looks like the factory shear panel. Anything that stiffens the joint between the tub and subframe will allow the suspension to work more efficiently without wasting energy on deflection/flex.

I personally love the process of modding my cars, and I'm really trying not to do it. I'm failing by the way.

Sector 111 has a car modification plan that is fairly well thought out. I have some reservations with their plan, but it's a great baseline if you ask me.

Easy for you to say Duane, you have all of phase 1 and 2 minus the power!

I don't have it ALL, but you make a good point. Might as well finish it up right? hahahaha

My only comment about Shinoo's approach is that power is last on the list...I've got a Cup 260 and I've got more power than the phase 3 setup on that list... AND I still feel that my car has got more handling than power. I feel that this chassis would be "balanced" with about 350HP...
I also think that having 400HP to 500HP would be hoot in this car! :D

power is always the last place to go.

another thing to consider is that a good set up to you as a driver when you are "slow" might become a bad set up once you get fast. - in other words, when you are slow you might think it has lots of understeer and try to tune that out. but put a fast driver in your car and he might say you need to fix all the oversteer.... so driver vs set up is always a moving target. so add into that that if your chasing power, but still haven't sorted out the driver - now you have 2 things your chasing - more and more power and driver learning to drive. typically, the driver will learn how to drive with less and less power. which is why many instructors (heck even successful racer will lap in say 3rd gear, and learn the track and start spotting your points - you have to start slow... and add speed by driving, not by adding power. again - why lots of the worlds best drivers start in "spec series" where the only way to pass is being a better driver. rather than passing with throttle (you can always add that...)

"roll speed" is the bottom of the data curve where drivers lose massive amounts of time on track. braking too much, too much throttle through apex because your going too slow. and giving up all that speed everywhere on track. the goal is to eliminate that bottom dip, and carry that speed. every car, is a momentum car! the guy that can carry more momentum will always pass you. in other words... its not the HP that makes you go fast. - case in point vettel frequently has the slowest car on track, but the fastest lap time. he can drive the chassis faster...

but back to the point that until you are getting good entry and exit speeds... you might be re-doing your set up - which is fine, just keep that in your mind that as your speed increases , you might be chasing changes (as you should be). if you add power before you do all that, you might never get the chassis "fast", if you just do the same slow things and keep adding hp on the straights to improve lap times.

so... i would in general terms, 100% agree with the sector 111 chart. spend a good couple long years in safety and handling phase 1-3... don't even worry about the other side of the chart :)

The "place" to go is the place you find most enjoyable...

Pontificating about "learning to drive" before adding power is just showing ones preference to what they personally place value in. Some people want the thrill of accelleration in these little cars and some want the thrill of perfecting their technique (better have telemetry if that's you)... Some people want both. There's no right or wrong. It's just preference.

As for the subframe stiffener... MANY places to better spend your money. Also, they all make the car much more difficult to service, with the tubular version being the heaviest most inconvenient. The panel stiffener is the preferred choice, but even still, stiffening that part of this already very stiff chassis is by'n large placebo part. Look to make that mod after the suspension has been stiffened, after the suspension bushes have been stiffened, and after your 6 point roll cage has stiffened the rest of the chassis...

That's why that shear panel worked for me... :D

Just come to the track with me! I get passed by 16 year old girls in stock Miata's. But I have a damn good time!
