IMHO.  I would suggest you consider getting a car with stick shift, it would be alot more fun than AT.  I simply wouldn't invest too much on a AT car except for exhaust, intake, but not suspension, and other important performance parts.

1> Don't worry about the brake for now, brake pads don't always improve braking power, as braking system these days are calibrated very well.  It's usually the brake fading problems which requires upgrading your brakes, or maybe the rotors.
2> My #1 suggestion is get yourself some of the best summer tires.  Lighter wheels would also help you accelerate and brake faster

Have fun!!

I am lucky enough that the OEM STi suspension is very stiff, and my upgrade with KW V3 Coilover actually improve ride quality and performance at the same time.  Therefore, it's not true that you can't gain both comfort and performance.  It's matter of rather you are willing to invest into some high quality shocks/spring setup or not.

Also remember not to just go low.

less body roll, more mechanical grip.  
if you want comfort, your trade off would be performance, if u want performance you'd have to trade off with comfort.  and really depends whats your tolerance ...

Seriously, if you are not going to get a diff car.  Just get yourself some good summer tires.  It will make a huge difference at every single corner you make fast or slow!  (Put in some swaybars as well)

For something fun to drive, but inexpensive + Potential (Get a 1st / 2nd generation Miata)

I would consider myself a newbie, but then I have read lot and lot the last few years  (mostly about my own subie), but would still like to share what I've learned so far.  Personally, I would only go for quality parts, instead of cheap solution for the looks.  And this is also base on street car, not race setup.

[quote]oh.... I SEE........

Question about lowering car... how? What parts are needed?

Spring? Struct? Coilover? Chamber kit?

To use lowering srings w/o matching with a good set of structs don't always provide better overall performance.  The correct combination is to get a set of high quality struct with springs with matching spring rate.  Coilover may allow you to gain the extra flexibility for adjustment the ride height.  However, getting coilover w/o doing a proper corner/weight balance can sometime upset the suspension more than you want.  Then of course you would have to do a performance alightment as well.  (Research and see what alignement setup works better with your car is needed).

Also lowering your car too much can also cause you other new problems, and may not necessary provide better performance than stock.  Remember you want to have suspension travel, so that you suspension can absob all the in-perfect roads out there.  Lowering the cartoo much can also ruin the roll center on a (MacPherson suspension setup)

My warning to you is: don't mistaken high spring rate/harsh ride = better performance.  A Porsche suspesion ride firm, but not harsh.


Camber Plate is for camber angle adjustment.  Assuming that tire would sit flat with 100% contact to the road with 0 camber, then this is what happen when you are at a corner.

Your car is turn right, the weight is transfer to the left side of your car.  The suspension on the left side is compressed  The Camber angle would go from 0 to possitive.  Therefore, less tire is in contact with the road.  Therefore, people pre-setup the amount of negative camber to help increase grip while you are cornering. eg. -2 on camber at rest, then 0 while it is cornering to max out the grip at the corner.


What brand? Eibach seems popular? for... spring?

I am sure others can tell you more, but I use KW V3 : http://www.kw-suspension.com/en/ ... Coilovers/index.php


Lowering = lower center of gravity... so it should, in theory, gives better for cornering while sacrificing ride quality?

So, again, while lowering = lower center of gravity, there are other factors in suspension setup that are more important than center of gravity.

Have FUN.

PS: This is what I have done with my 06 STi

Cobb AP + Protuned on mustang dyno

280 WHP @ 5500
296 WTQ @ 4500

- SPT Intake
- Cobb Turboback Exhaust w/CAT
- KW V3 Coilover (Lower .75" - 1"
- RCE Camber Plate (-1.5F / -2.0R)
- ACPT Carbon Driveshaft
- Cobb F/R Swaybars Cobb Endlinks

I have my doubts with something this inexpensive..!  Have you consider TEIN?  They have something like this for the TSX: http://www.raceinspired.com/ps-9 ... ra-tsx-2004-up.aspx

LOL!  I think you are quite right!  Afterall, I know too little about Honda/Acura...!  Stuffs for our Subaru are usually more expensive..!!  But then I still like to stress how quality parts come to a price!

I used to think ride confort = less performance, until I had the chance to ride on some other high quality suspension setup =P

BTW:  What about the Tein basic?  TEIN setup on our STi usually ride pretty stiff..

I have RE01-R (New one is the RE-11).

The RE01-R is excellent in RAIN/Wet + quite confortable/Quiet

Kumho XS is a bit faster than Star Specs wor? Should be cheaper as well.
