The Hotchkis Tuning anti-roll bars can be purchased as a kit or separately. Either way, they come with all the necessary brackets,bushings, hardware, grease and instructions. The front bar, on the bottom, is 24mm in diameter. The rear bar is slightly thicker,at 27mm. Due to their hollow construction, they're only slightly heavier than the stock bars, despite being significantly stiffer.
ANTI-ROLL BARS
The Hotchkis Tuning anti-roll bars are constructed of hollow, mild-steel tubing and are powdercoated to prevent rust. The hollow bars are lightweight without sacrificing rigidity.
Both the front and rear bars have three positions of adjustability. Positioning the end links inward increases roll stiffness, while moving them outward does the opposite. Depending on the setting, the front bar ranges in stiffness from 40- to 68-percent stiffer than stock. The rear bar increases stiffness from 273- to 338-percent stiffer than stock.
If you don't have access to a lift, then you may want to reconsider installing Hotchkis Tuning's front anti-roll bar yourself. It's about as difficult and time-consuming as bolt-ons get.
The crossmember needs to be lowered about 3 inches to finagle the old anti-roll bar out and the new one in. Support the crossmember and remove the two nuts in the front and the eight bolts in the rear. Remove the single nut and four bolts that fasten the rear engine mount to the crossmember. The four nuts holding the steering rack to the crossmember must also be removed from below.
Before the crossmember can be lowered, the plastic splashguard beneath the front bumper must be removed. Once out of the way, the bridge bracket running from the radiator support to the crossmember is exposed and can be unbolted.
It's easiest to pull the old anti-roll bar out and slide the new one in from the driver's side. First, unbolt the two brackets and remove them from the bar. Slide the new bar into place, snap the supplied bushings and brackets onto the anti-roll bar and bolt it to the original holes in the crossmember. Be sure to lube the bushings before sliding them on.
When reinstalling the crossmember, partially thread the nuts and bolts a few turns before tightening anything down. Tighten the steering rack nuts next. Reach above the rack with a wrench to keep the bolts from spinning.
Thankfully, installing the rear bar is much easier. The procedure is similar, only there's no crossmember to drop. When removing the nuts that attach the rear anti-roll bar to the end links, insert a 6mm Allen wrench on the back side to prevent the ball joint from spinning. Unbolt the anti-roll bar brackets from the rear subframe and drop the driver's side end down first. The Hotchkis Tuning anti-roll bar slips in the same way, right over the exhaust pipe.
The nut in the center must be removed to drop the crossmember. To access it through the hole in the lower control arm, use a 19mmsocket and an extension. | 
These are two of the four steering rack nuts. Their torque ratings are only 45 ft-lb, but they feel like much more. The base ofthe nuts feature anti-slip grooves that grab the metal and make them difficult to loosen. | 
The front splashguards must be removed in order to access the bolts for the bridge bracket. A series of plastic screws and rivetsmust be popped out in order to remove the two pieces. |
Notice the gap between the crossmember and the frame. If the crossmember is lowered this much, the stock anti-roll bar will haveroom to come out. | 
Since clearances are tight underneath the tC, it's best to wait to install the bushings and brackets until after the bar isfinagled into place. Hotchkis provides grease for the bushings. Use it to avoid squeaks. | 
Looking from the passenger-side wheel well, be sure the anti-roll bar is located on the inboard side of this power steering hose.Positioning the bar on the outer side will ultimately kink the hose. |
Grease fittings are integrated into the new anti-roll bar brackets to add additional lubricant. New hardware is also included. | 
The Hotchkis anti-roll bars offer three-position adjustability. For maximum roll stiffness, bolt the end link to the innermosthole. Moving the end link outward decreases stiffness. The front bar can be set to a maximum of 68-percent stiffer than stock andthe rear a maximum of 338 percent. | |
