Strengthening the Weak Link in the Chain

Tomioka Close Ratio Gearset Subaru WRX

Subaru’s have proven themselves on the rally circuit, the track and the street as fun to drive, easy to modify, and easy to own enthusiast cars. The once utilitarian brand has emerged as a cult car, and has a massive following. Any go-fast goodie you can think of is offered for these awesome vehicles. With increased power, you soon find the practical limits of the surrounding parts. The one part that seems to be plagued with problems as torque and horsepower is significantly increased is the transmission.

Thankfully, Tomioka Racing has their 5 speed semi helical cut set available for the 1998-2005 WRX. It uses a SNAM420 Alloy steel, to give terrific strength, and smooth shifting, without the whining noise of a full straight cut set. This is a very close ration gearset as shown by the ratios:

1st 3.272
2nd 2.285
3rd 1.667
4th 1.238
5th 0.958

Priced at $2442 + shipping. Comes complete with all parts shown. Contact us at z1sales@z1auto.com to order yours.

Opposites Attract

These are new and now ready to go! ATS Japan’s ultra strength magnetic drain bolts for the oil pan, transmission and rear differential of your 350Z/G35!

These bolts are direct replacements for the factory units, and feature very strong 3,500 gauss, neodymium magnet for greater strength and durability. With an adhesion strength of up to 2.8kg, this product removes a greater amount of iron particles, thus extending the life of your vital engine components. The standard magnetic drain bolts tend to lose the magnetic force rapidly in a very high temperature environment. ATS magnetic drain bolts last much longer under the sustained high heat environments of even the hardest core track cars.
