double a-arm suspension....

Audacity Racing · Post by **Audacity Racing** » Wed Jun 15, 2005 10:47 pm

well... i bought a new car... a 2k5 Toyota Corolla XRS with the TRD supercharger (had to buy it extra and put it on myself... it's for the scions though)...

anyway...

i'm converting the woo to a full race car now for solo I and solo II races with the scca as well as some of the semi-pro races. for the suspension i want to convert the front to a double a-arm with coil-over between them and the rear to a double a-arm with pull-rods. i know it's gonna be some mad fab, but do you guys thing the effort is worth it? part of the process is going to be making a steel inner-chassis for everything to mount to and i've been thinking about making it awd if i can do it easily while re-doing everything with the car. the new inner-frame will be a drift-style cage with major suspension mounts on the front and rear as well as engine mounting and transfer case, if i go awd. any comments??????? later i'll post the final design for my turbo manifold... everyone say bye bye to the egr!!!!

sound cool man. i don't know too much about suspension except for the basics but if you build they will come.

hey just a newbie question, that i should probably know by now, but what is the EGR and what does it do?

egr = exhaust gas recirculation, it's used to prevent the engine from operating at a high enough temp that oxides of nitrogen aren't created...

if you introduce "used" air into the combustion chamber, then you have inert gas that is just taking up space and not burning, thus you can't get high temps inside the chamber. the egr valve is used to take some of the exhaust gas and put it back into the intake to prevent these dangerous gases from being formed. oxides of nitrogen are the main components of smog... the visible kind that is so horrible to your health. the planet would prolly be dead now if not for the egr valve on modern cars...

anywho... does anyone have any idea how much the weight of the interior, glass, and the rear suspension is? i know that's kinda weird to ask, but hey... who knows... someone might have taken it off...

Wouldnt that put you in the class that has alot of really fast cars (cant remember what the SCCA class' are)... but things like that usually put you in class w/ like race miatas which kick ass in solo2

well.... that's kinda what i'm hoping for... to be the first woo to go to the run-offs for competition

actually... i'd run in the class with the cobras and kit cars... cause it would be so much off the wall... hell, i might be in a class of my own... hahahaha

For double a arm setup your gonna need to build a frame to put the body on. The stock suspension just bolts to the body. putting a double a arm on itwould not work.

read above about the steel sub-frame...

so, after some heavy design work, i have chosen a pull-rod suspension in the front. i got the analysis done today on the lower control arm and just thought i'd show everyone what i was talking about. remember, this is the lower arm (symetrical on both sides)

:twisted: and... the upper arm
