Suspension mods:

Both 1zz & 2zz -

Springs: Eibach, Tein, Progress, Hotchkiss, & TRD are the main brands that most people prefer.

Coilovers: Tein SS, TRD, K-Sports are the choices.

Front Strut Bar: DC Sports, TRD, Megan Sports, & the OEM Corolla XRS

Front Sway Bar: Hotchkiss & TRD - as far as I can recall.

Rear Sway Bar: TRD, Progress, & Hotchkiss

Motor Mounts: ESMM

Another equation to the suspension is the tires.

The OEM Matrix tires - especially the Continentals suck!!! Only last about 15k miles before they go dangerously bald!!!!

OEM rims that fit the Matrix:

(5x100 bolt pattern)

The Scion TC (17s & 18s) & Celica GTS (16s)

P;ease add more if I have missed any.

Could take out the cats... won't pass smog, but you can always put them back on.

There is a high - flow cat. from Magnaflow

Exhausts available for the Matrix:

Magnaflow - the ONLY full cat-back exhaust on the market.

All the others are axle back - meaning one would need to do a full custom piping from the cat. after.

Borla - probably the best

TRD - rebadged & overpriced Borla

GReddy - one of best sounding exhaust

Intake Manufacturers for the Matrix:

2003 - 2004 can use SRI (Short Ram Intake) or CAI (Cold Air Intake).

2005 - 2008 can use SRI, but CAI cause a CEL to appear - system running too lean. I believe Fujita and maybe Injen make a CAI for the 05 - 08 that does not cause a CEL to appear.

2004 XRS have an air pump, that partially gets in the way of installing a CAI.

SRI produces a little more power off the line.

CAI produces a little more power on the top end.

If you are in a flood prone area - I would suggest you use a SRI - to avoid hydrolocking - a few rare instances have occurred with a CAI - AEM does make a Bypass filter if the filter does get partially submerged.

But why would anyone want to cross a heavily flooded area anyway?

SRI manufacturers:

K&N Typhoon - best "sounding" SRI

AEM SRI - comes w/ the AEM Dryflow filter, filter can be bought seperately and installed w/ other brands.

Weapon R - not as widely known. Comes with a heat shield.

CAI manufacturers:

TRD CAI - if installed by dealership, warranty is valid.

AEM CAI - comes with the AEM Dryflow filter, filter can be bought seperately and installed w/ other brands.

Injen CAI - some have stated the best "sounding" intake

Fujita CAI - still new but are reputed to be an excellent brand

A little update:

Borla has discontinued making the axleback exhaust for the 2003-2008 Matrix.

You may still find some on ebay or other Toyota sites used.

Vibrant does make an exhaust for the 2003-2008 Matrix as well as GReddy (DTM).

Both are axleback but you can custom make piping from after the cat. to the axleback muffler.

Vibrant is just a tad "throttier" than the OEM exhaust and the GReddy sounds very nice and smooth - not Honda fart can loud, but low and deep.

Rims:

The 2003-2008 Matrix have a wheel offset of 5x100.

The 2009 models (not the XRS) also have a wheel offset of 5x100.

The 2009 Matrix XRS has a wheel ofset of 5x114.3

Some Toyota rims that WILL fit on a 5x100 wheel offset:

Toyota Corolla (2004 - 2008CE, LE, S, XRS (same as Matrix 16's).

Toyota Celica GT (15 inch) and GTS (16 inch)

Scion TC - OEM 17's and 18s.

The Scion TC 17 inch rims are actually 2 lbs. lighter than the Matrix OEM 16s.

Tires to fit the rims can be calculated to the same wheel diameter via:

I hope this helps current and future Matrix owners.
