So after driving the car hard a few times i realized there's this awesome oversteer that sneaks itself in towards the end of a turn. I've never experienced this in a FWD car and i'm very happy about it. Is this due to the multilink rear or the weight distribution of the car being towards the front?

my sc, which had lots of suspension modifications was very stiff and gripped very neutrally with a predictable understeer at higher speed. unless you gave it more throttle, that's when the rear end would start to come out, so this behavior is very surprising to me.

anyways, what else do you like about the driving of the car?

stiffening the chassis is definitely a good idea, but messing with spring rates i'd wanna be careful, this car right now is set up very very well, the only other FWD hatch i've driven that handles like this was a Fiesta ST, but even that understeered more. I wanna lower the car but want spring rates that are very similar. Are there any coilovers for this car or the TC with swift springs?

I think at one point Scion USA was rolling around with a modified Scion iA and Scion iM, both were lowered with a few other mods, you might want to do some research on that iM, maybe it has what you're looking for.

Then there were also those Scion Tuner Challenge builds.

just googled the tuner challenge, and both of those are on air suspension lol. i see BC coilovers make swift spring options for the TC2, but they're almost 1200 bucks. i'll keep looking.

The stock suspension is one of the best parts of this car.

Waiting for a front strut bar in the mail.
I agree.... 2 days ago, I to go palomar mountain due to freeway closure... i was going through turns uphill and downhill and I did not even realize I was going a little to fast than I should be.

the iM Chassis is the same as the Lexus CT200h and overseas Corolla/Auris so all them Suspension Parts should fit ok on the iM.

I am just planning to get Lowering Springs & RSB

I have already tracked the car at a few SCCA / Autocross races, and been on some pretty awesome drives up in the mountains of VA and WV. I have only experienced understeer which is normal for a FWD car. I have yet to lose control of the car, but have had the tires screaming often, the traction control has kicked in multiple times (highly annoying, even if you turn it off it will automatically turn back on in less than 15 seconds or so), but I am very curious to know how you got oversteer out of the car (what were the driving conditions). Are you still 100% stock? The body roll on the car at stock height was a bit scary, even with the H&R sport springs the car still leans hard. I would really like a bigger rear sway bar for the car, and some of the TB Performance chassis braces too.

yea i'm completely stock, it would happen on exits and some curvy roads. to get it to oversteer i usually use the lift off technique which gets the rear unweighted and pushes it forward. then power out and the car feels almost like it's AWD.

So you're intentionally creating the oversteer, gotcha. I was a little confused there for a sec.

Good to know. I used this technique on my celica and it works good, even resulted on a spin out going down hill.

I baby the iM too much :p
