I don't suppose you have any proof of your comments about the strut brace being a complete waste of time. Pretty rash statement if you don't have a strut brace fitted.
My MPS6 is fitted with a strut brace - my sons stock MPS3 lifts a rear wheel when turning into our street, even at slow speeds - why would you want "the arse end to be even more torsionally stiffer" Some strange opinions you make.

your kidding right? did you read what i said..
they have a Factory Strut brace in the 3MPS
My Car cocks its rear leg left right and centre.. Basic FWD Tuning Dictate Stiffer rear Softer front.. unless of course say its a soaking wet day at the track then you would be better off getting under your car and unhooking one end of your sway bar at the rear so the back end becomes a little less lively.
I always have tuned my Front Wheel Drive Suspention Setup Softer in the Front and Super Stiff in the rear.. weather you do this thru spring rates / more intense rebound on your shocks or purely thru basic tyre pressures..
i still think doing either end of the car is a waste of time.. its more of a Aesthetic than anything.. i used to make strut bracing for my cars.. front and rear i think they serve no purpose especially in a car that already has the ability to have one side lifted up nearly dead level even when jacking from the front most jack point..

Not kidding - strut braces prevent flexing of the strut towers, not a REAL problem in MPS's as the close proximity to the firewall and the plates to the firewall, but the plates are pretty thin.
I have had huge improvements in my old 200SX with a brace then the SS Commodore and now the MPS6. Over the years also have made strut braces, in particular for Auto apprentice students Commodores - mainly to stop the towers from leaning in and creating huge negative camber. Made one for my Rally Escort for the same reasons - made a huge difference. Escort kept good camber readings until a jump on Kangaroo Island bent a strut, but the towers never moved.
I have no idea about the MPS6.. but my car is like a see-saw going into steep driveways on an angle.. its braced from factory to the hills.
And the OP is an mps3 driver....

The 6 doesn't have the see-saw effect! - I think Doc you could register that
See-Saw Effect ® by Doc
Anyway back on topic, the 6 has more give (even with the coilovers) maybe because it's some 200kg+ heavier than the 3 and whilst Mazda added more bracing see pic, it still felt like there was some flex in the body.![]()
Sorry don't have a pic for the 3

Personally, i dont have an MPS but i did add a whiteline strut.. and found very little difference in the way the car handled [the car turned in marginally better.. but i got more of an effect with my rear swaybar]... so i sold the part and used the cash to spend on springs + shocks... and its AWESOME.
I also doubt the car needs more bracing.. my car in my gfs garage can be a dualpod?.. dunno the word... the front left + rear right wheel can be in the air at times which is scary..
