Here is how to convert between the two.
N/mm = lbs/in / 5.709
lbs/in = N/mm * 5.709
So,
25.5N/mm*5.709=146 lb/in
45N/mm*5.709=257 lb/in
Great Post!!!!

I know you've probably heard "Great Post!" about 50 times, but your gonna hear it again..

Thanx for going to all the trouble to research this stuff! Now that I know all this, I'm kinda afraid to change anything!

Suspension & Handling:

- It uses a torsionally rigid unit-body chassis.
- It uses a MacPherson strut front suspension, with a full subframe that supports the suspension links for stable handling. this isolates the body from road noise for increased comfort, as well as providing excellent turn-in and response.
- The front anti-sway bar is 21 mm.
- The double wishbone rear suspension is similar to the avensis, but is mostly derived from the late celica. A-shaped control arms and rigid upper arms connected to the subframe provide low unsprung weight.
- The rear anti-sway bar on an automatic is 20 mm thick. on a manual, 18 mm.
- The stock spring rate in the front is 25.5 N/mm. The TRD springs provide 29.8 N/mm.
- The stock spring rate in the rear is 45 N/mm. The TRD springs provide 57 N/mm.
- There are 3 lateral reinforcement braces not found on cars in this class. They run across the rear floor deck, and in front of and behind the rear suspension to reduce overall flex.
- The stock 17 inch wheels use a 45 mm offset and a 5 x 100 mm bolt pattern, with 215/45/ZR17 (same tires offered on Lexus IS300)
- The tC uses aerodynamic fender spats to route airflow under and around the tires. This reduces wind noise and increases high-speed stability without compromise to the brakes.
- The 4 wheel disc brake system was designed to feel like a european compact.
- The tC uses 10.8 inch vented rotors in the front, and10.6 solid rear rotors in the rear. The parking brake is an internal drum.
- There is a 2 step "booster" in the brake pedal to improve reponse and feel.
- The tC is equipped with an electronic brake distribution system, which measures minute amounts of wheel slip to transfer braking force from front to rear as well as side to side.
- The tire pressure monitor system measures wheel speed at each wheel, and uses the outside ambient temperature to compensate correction for density. if a tire's pressure is low, you will be notified by a signal in the instrument cluster.
Hope this helps your understanding the car's dance moves.

And that's it for the FAQ, for now. Keep in mind that this FAQ covers the stock car more or less. I hope it helps alot of you young drivers with a better understanding of your car. I also hope that it helps experienced drivers appreciate the work and creativity put in to make this car something special.

- The tC braking system is virtually identical to that of the Celica GT-S. In fact, brake rotors and calipers are the same, and most big brake kits for the Celica GT-S will fit the tC.
- The front upper strut mounts on the tC are connected to the A-pillars and firewall and include extra gusseting to provide an exceptionally stiff front suspension.
- The exhaust manifold is made of stainless steel and has an integrated catalytic converter.
- The tC has more sound deadening material than anything built by Toyota that's not a Lexus.
- For those with the factory VSE Bazooka subwoofer: It is mounted only to the side of the car and the cover over the spare tire and tools is easily removed when you need to get to them.

does anyone know how to bypass the DVD player for the factory navi system. i already took care of the EBRAKE sensor, i tried cutting the REV and SPEED wire. the DVD player works like a champ when not moving but as soon as i hit about 8 mph, i have no picture but still have audio
any ideas on how to fix this?
i have posted concerns about that black box that is available through alpine, someone replied that it doesn't fix the problem. can anyone verify this or protest it.
thanks!!!!!
