Tein Basics arrived earlier this week.. Installing on Saturday... Will upload more pics later...

nice man how low are you going to go in toronto.

say what?

Going for one finger gap all around... so however low that is...

Nice man I kept the front of mine about 9 threads from the bottom and back only 5. Since their so much weight in the front I needed that difference to clear some steep driveways in nyc.

Not to mention my body kit takes a beating when i had it a bit lower in the front.

^ aaghh, i know what you mean. everytime i go into/out of my parking garage in downtown charlotte, THE ENTIRE UNDERBODY OF MY CAR SCRAPES

Not trying to rain on anyone's parade, but with those drops, your roll center is probably ten feet below street level and your roll couple is probably ten feet long. (I'm exaggerating.) It may look the way you want, but in terms of body roll you're negating the effect of higher spring rates and likely introducing MORE body roll.

I installed Tein Basics on my TSX, too, but only dropped the car about 0.75" to maintain the upward angle of the front and rear suspension arms and limit the increase in roll couple. I'd bet that's a big reason why A-Spec and other factory suspension upgrades only lower the car by a relatively small amount.

Like I said, not trying to tell anybody they're doing something stupid, only pointing out what a lot of people don't know about center of gravity, roll center, roll couple, and suspension geometry, and the adverse effect on all four from lowering a car.

So... don't stop there.
Tell us about all of the adverse effects, illustrate your point.

So you say it will increase body roll, is that it?
Give us some specifics please.

What you are saying makes no sense. I am very positive that the engineers who designed those performance suspensions took into consideration terms such as “center of gravity”, “roll center”, “roll couple”, and “suspension geometry”.

Every car is different, every suspension is different, every setup is different but they all follow the same Law of Physics:
The lower the Center of Gravity to the ground, the greater the roll Over Angles.

The greater the roll Over Angles the greater the vehicle to remain stable and unlikely to roll over

Example:
2" drop > 0.75" drop
a car with 2" drop has a lower Center of Gravity then a car with a 0.75" drop
Therefore the 2" drop car will have a higher stability and cornering agility

to the OP your car looks great with the drop

say what?

Got a question for other's who have lowered their car with Tein Basics... Are the number of threads showing on left and right side of the car equal to each other (i.e left front = right front and left rear = right rear)?

My fronts are 9 threads from the bottom
back are 5 threads from the bottom.

Since the fronts a bit weight heavy I wanted to keep the front higher than the back To get up steep driveways. (normally I have no passengers)

Yessir... nice drop

A lower center of gravity (CG), all other things remaining equal, would decrease body roll. The problem with your theory is that all other things don't remain equal. When you lower a car, you don't just lower its CG. You're also changing the angles of the suspension components relative to the car's body and wheels. The axis around which a car's body rotates, or "rolls", is called the roll center (RC). The RC is determined by those suspension angles that you just changed. As the car goes down, the RC goes down faster than the CG. The greater the distance between the two (called the "roll couple"), the more body roll you get in a given turn or cornering maneuver.

Higher spring and damping rates offset this somewhat, but not entirely -- especially with relatively mild rates like in Tein Basics combined with a big drop.

Engineers making adjustable coilovers understand all this stuff. But there's nothing they can do about how your suspension geometry changes as you lower your car. It's up to you to understand how things change when making changes to your car. So, I'm glad you're asking questions. Hope this helps.

I'm no engineer, so please, engineers out there, help me out.

HERE'S a good thread discussing these concepts by people smarter than me.

PittIsIt

what was the cost? did you install yourself? If i had someone do it, how many hours would they charge?

Should be no more than 2 hrs with a shop
hr rate here in ny is 80 an hour.

say what?

$880 for parts
$200 for labour
$80 for alignment

Nice..
