For the most part, I really like my tC2, but there is one thing that really bothers me. When I hit a bump in a corner, I feel like I'm losing some control over the car.

Does this sound at all familiar?

Suspension issue, or floppy unibody issue?

The first thing I did when I test drove my 14 was take it quickly around some back roads. The car was floaty/nervous feeling. So yeah, the tC is too soft for the weight.

A few things will fix this.
1: better shocks, stiffer/faster valving but you'll loose comfort.
2: stiffer springs. Again, loose comfort.
3: lowering springs. Will help a lot, but will loose some comfort.
4: sway bar upgrades. Pricey, but worth it for hard cornering.


For a budget minded set up, I'd suggest going with Raceland's. They ride great for coilovers. A bit more firm springs, but mild valving on the shocks to provide a good comfort and performance balance. However, they aren't great for hard driving (back road, cannon runs, mountain touge style runs, auto-x, road racing).

Running Racelands on mine, and have been since the 2nd week of owning the car. I drive with them maxed out with one collar removed to get a extra half of an inch drop. I can drive somewhat hard on backroads and get great feel, and response from the car. However, I can easily surpass the limits of these coilovers due to the valving of the shocks.

I've been researching DIY alignment, and I'm reading that caster adjustment can fix a car that gets squirrely after hitting a bump. It might be that what I need most of all is a caster adjustment.

Still considering BC Racing coil-overs though.

Usually the OEM suspension specs are set for optimal safety standards. I'd look into upgrading the springs, shocks, or both then resetting to factory alignment specs minus ride height. Even a small 1" drop will do wonders for handling. There is a lot of weight on the top side of the car with the glass roof, so by getting the center of gravity lower, you'll improve it.
