FAQBrake Components
Hawk Blues have great initial bite, but are hard on rotors. PFC 97’s have less initial bite, easy on rotors and have a significantly longer life. For Spec Miata’s we are now selling more PFC pads then Hawk’s. We have race winners using both, it’s simply your own preference. Radiator The KOYO 53mm Radiator is the best I have found. It fits perfectly into the factory mounts and the fans mount properly. Minor clearance of the bottom of the fan shroud may be needed for sway bar clearance. Fluids & Oil We use the following fluids in all of our Spec Miata's
Transmission Transmission and differential removal and replacement tips. First thing is to drain the fluid and disconnect the battery. The front of the PPF is straight forward. The rear most bolt on and the differential has a special nut on top that locks the differential in place. After removing the long bolt, reinstall it about 6 turns. Then hit the bolt upwards with a hammer. This will remove the special nut. Do not loose the special nuts, as they are not available separately. Advanced Autosports has had replacements made, just in case. The forward bolt on the differential is just like the rear one, except it has a built-in shoulder. Remove the front bolt and use the rear bolt to drive out the special nut. The front bolt also has a lower bushing that must be removed. A chisel or pry bar will remove the bushing. Now the PPF can be removed. Once the PPF is removed the trans will tilt back far enough to give access to all the Bell housing bolts. The big trick is to place a 2 x 4 between the steering rack and the engine. This will keep the trans tilted back during install. Seats What size seat do I need? If you consider yourself to be skinny, get a 15” seat. I wear 38” waist jeans and use a 16” seat. Really big boys use a 17” seat. Cool Suits Once you try a Cool Suit you’ll never run without it again. Have you ever noticed your mind wondering (and lap times slowing) at the end of a race. Driver cooling helps eliminate fatigue and lack of concentration. I highly recommend having a set of replacement fittings in the trailer. The day you’ll need it will be the hottest day of the season. Steering The stock Miata steering wheel is approx 14 inches in diameter. The 320mm wheel is approx 13 inches in diameter. The Personal 320mm and the 13" aluminum wheels are our biggest sellers. For those with strong arms or a need for more cockpit room the 290mm wheel works well. The AIM wheels are designed specifically to mount the AIM data display screen on the steering wheel. |
