how to improve the handling of a prius c? need some advice!

kind of.... Less sidewall flex from the higher pressure in reality

 

On stock original cant pass corners with many S curve at speed more than 7okm/h because i need keep braking the car head to much understeer

Now after putting the following bars
1) UR front strut
2) UR front lower
3) UR mid
4) UR rear lower arm
5) forget the brand room bar
6) Spring cushion

Comfort does drop a little for me
Can take corners faster without braking at speed no more than 100km/h however the rear fill is gone spin if i go faster

Anyone have idea, if add rear antiroll will it help? if not enought side rear bars will help?

 

Trd rear sway is nice!

SGH-T889 ?

 

Just want confirm rear sway is another name for antiroll bar?

 

Yes

SGH-T889 ?

 

I have extensively searched but cannot find TRD rear sway for prius C. I only found Whiteline and Cusco or did you use one for Yaris? Any help on sourcing would be appreciated as my driving habits make the PC handling dangerous. From what I have read the rear is the best place to start and the Whiteline looks good except the rinkydink looking U bolts and the Cusco I do not like at all and the TRD I have seen for other models looks good. Cheers

 

The trd rear sway fits newer yaris, all scion xD and a few overseas models.

 

i would like to RAISE my c about 1 inch or should i just yank that black rubber lip hanging down from the front bumper, ??? hhmmm i would still like to raise it about one inch,,,, or raise the driver's seat one inch instead (how about two inch raise to drivers seat?)

 

To each their own I suppose...

 

Don't rip that rubber strip off the bottom. There's quite a few screw holding it on and you'll do more damage than good.

Add two or three inch upholstery foam to your drivers seat.

 

ok, i hope running over some curb stops dont rip the rubber off for me. a seat pad (perhaps a phone book or two) is the kind of simple solution I like. thankz

 

is it PTR11-52071?

 

^^^I'll 2nd this post. Is that the correct part #? Just found the part for $145.60. May be worth pulling the trigger after all. Anyone want to post a close-up pic with their bar installed? A pic where the bar mounts to either side? The instructions don't have a picture and the pic I have from the link below is too small to really be able to tell what I'm looking at exactly.

Can't find when/where I bought it but yeah that's it. We basically have a mish mash of yaris and xd suspension. Only real difference is rear shocks and hubs.

 

simple way to improve handling is not to over inflate your tires... I just realized this after lowering the air pressure of tires below 40 psi... for the first time.

It handles way more stable in straight line and turns... but I'm losing about 5 mpg... and I don't like that!

 

I just installed camber kit in addition to TRD and the amount of grip on stock FuelMax'es is impressive. Yes it can go around corners much faster, and depending on dynamics either front or rear outside tire can slide. BUT as a result too much body roll, to go beyond this need to lower car and get better shocks. In other words Tein coilovers are due.

15mm kit is $20 and takes ~1hr to install, depending on how easy to undo 3 nuts per side. I corrected the toe-in but it looks like I either to dial back on neg camber or toe-out more.

 

15mm rear hub spacers? How many degrees camber? How much? Do they offer zero degree camber ones? How much gap side to side between wheels and fenders is there now?

 

No we put camber kit on front; not a spacer. As was car was understeering due to less grip in front than in the back, so there isn't any reason to improve rear grip.

Kit is marked as +-1.75deg and I put it on max negative camber. The OEM alignment was -0.5deg on left and -0.9deg on right to compensate for road crown, so if you take 1.75 as gospel it should be -2.25/-2.65deg. I left rear untouched at -0.7/-1.1. Need to find printout and check the numbers. Gap does not change b/c all kit does it tilts front wheels in.

Now the problem is that on MacPherson (picture your favorite pic of Elle) adding neg camber results in additional toe-in. I have compensated adjustment 1 turn, but it looks like it needs more. Would be nice to go and put it on stand but alignment costs about x15 time what the Torque app costs, so..

Here is the one we used ($20):
Specialty Products Company 81270 EZ Cam XR 15mm Adjuster Bolt
item # B000CB3QTO on Amazon (priuschat destroys links)

Tilting wheels DOES change gap. Then again I'm coming from the Hella flush/fitment crowd

 

Ps you're getting ripped off for alignments if they're choosing you 75 bucks. As we can only REALLY Ajay the front. Look for a two wheel alignment place, should be less than 50. Then again in spoiled by my buddy working for the best local alignment/tire shop around and only getting charged a case of cheap beer to do it
