fwiw, recently i have tested a m3 and my 335 back to back at the same corner a few times
both cars have the same tires (bridgestone re71rs, 18 inch wheels, 255/265 on 335, 245/275 on m3)
(m3 has stock front control arms, full set hardrace rear control arms, nitron r3 suspension)
(335 has turner monoball m3 front control arms, full set hardrace rear control arms, turner solid alu rear subframe bushings, mfactory lsd, stock sways, ast 5200 suspension, rear poly top mounts, solid bottom mount)
difference... alignment and spring rates, the m3 is a 8/10k spring setup, running stock front camber/toe, i think -2 or 2.ish camber in the rear, i am running 9k/14k spring setup, -3 front camber and -2.6 rear camber
with dsc off
m3 will understeer at the limit (as expected), front and rear feels planted and communicative the whole time, however, i could not put the power and have the rear step out and have to lift until the car stops understeering
my 335 is setup to oversteer at the limit, front feels pretty similar but the rear..theres room to improve on compared to a m3
with that being said, i have the rear m3 braces sitting at home, i am just waiting for the ultraracing center brace to come so i can get it installed
i also got the hardware sitting at home to make and install the the front subframe braces like the one in the first post
dont hold your breath for an update though, i will eventually get around installing it... but ive been lazy and playing with other stuff
Any news on the ultraracing brace?
God no. Not in any way. But man was it alot of fun.Did it impact like you hoped?
Will have a look at that Porsche engineering art ;-)
I have done most like you mentioned front rate: 350, rear 750, JRZ suspension, Drexler, Camber plates, M3 bits, m3 bars, all mounts. (will change the bars for a slightly stiffer and more neutral set.
I do sense some potential for extra stiffness mid car, on the other hand, I plan to install a cage next year, that also might take care of extra stiffness and the bars will also impact the overall dynamics.
Best track improvement is my brake config (together with the suspension), ebc pads, zimmerman disks, copper end pieces where the brakeline enter the calipers, proper brake fluid, and decent brakelines topped with some custom front feed brakeducts. The ducts gave me 20 minutes extra laptime before cooldown,in the past it was one big melting party at the front brakes.
Any how, a bit off topic ;-)
So will take UR chassis bits of the list... will spend that money on a dry-sump like solution...
God no. Not in any way. But man was it alot of fun.
Doing stuff like stiffening up the suspension arm bushings, anti-roll bars, suspension and tires offers a much larger difference to the driving experience. Not to forget engine mounts.
Check out the golf ball design of the undertray of the new cayman gt4 for some professional sillyness instead. I believe engineering explained has a YouTube video about it.
