Like any other Honda, dropping the TSX meant the suspension's camber and toe would change, which also meant the Potenzas would be toast before too long. Eibach provided us with SPC Alignment adjustable ball joints for the front upper control arms and adjustable camber links for the rear. The ball joints replace the factory-issue and offer 1.5 degrees of adjustment, both ways. The OEM ball joints need to be pressed (or severely beaten) out, but the SPC ones slip right in and are held in place by the adjustment nut on top. The ball joint's design makes camber adjustment easy; you can even leave the wheel on the car while making adjustments. The rear links replace the factory, non-adjustable ones and are already fitted with a replacement ball joint. The links feature opposed threads on each end, which means camber adjustments can be made with the link on the car. When installing the rear links, be sure to match them up to the factory ones lengthwise to ensure against any dramatic camber changes if you don't plan on doing the alignment yourself. The SPC rear links offer 2 degrees of negative adjustment and 4 degrees positive.
The TSX is no rocket, but moving and not being able to stop properly never did anybody any good. Not that the TSX doesn't stop well now, because it does, but we'll be stepping up the power slightly in the near future and Arpon does drive a little crazy. EBC Brakes and Goodridge tag-teamed the TSX brake system with EBC 3GD vented rotors and Greenstuff pads, along with steel-braided lines from Goodridge. The gold-plated rotors do more than look blingy behind the RonJons though. The directional, slotted, and dimpled rotors help keep the braking system cool, which means better stopping. EBC's Greenstuff pads are the perfect compromise between something that can be used for a daily driver and something that'll see the track on occasion - not that the TSX will ever see a track though. The Greenstuffs are not just a hard-working pad, but the residue and dust left over by them is easier to clean off wheels when compared to other pads, which ties in perfectly with the whole VIP thing. Face it: All pads create dust, so you might as well find ones that are easier to deal with. Finally, we firmed up the pedal feel with Goodridge steel-braided brake lines and EBC DOT 4 brake fluid. Unlike OEM DOT 3 fluid, DOT 4 has a higher resistance to moisture and temperature, which simply means it can take more of a beating. Does Arpon need it? Probably not, but there's no harm in overkill.
