Customer Testimonial

Hi Paul,

last week i ve tested my gtam with a lot of modifications and your Brake/ClutchConversion Kit to Tilton; now is a very fast car, Tilton Kit is good for much improved braking.

Thanks for your help

Ciao RT (Italy)

The Tilton pedal box is working great. Improved my lap times last season with average of 2 seconds. DH(Netherlands)

Performance.  The dual Tilton master cylinders provide incredibly positive braking with normal pedal pressure applied.  No vacuum boost is needed. The increase in stopping power is unquestionable. 

Economy.  Throw away the super expensive ATE booster and master cylinders.   You can buy a new replacement Tilton master cylinder for the price of an ATE master cylinder rebuild seal kit. You can buy this conversion kit for the price of the booster, brake and clutch master cylinders. 

Details.  The firewall adapter plate positions the pedal assembly in the same location as all 105/115 cars with hanging pedal assemblies.  This 3/8" aluminum adapter plate allows you to bolt on the Tilton firewall pedal assembly. Before the pedals can be "bolted" inside the car, it is necessary to cut away the booster pocket and remove the lower 6 inches of the steering column support bracket. We provide instructions but this is one to two day job.

List of kit parts:  adapter plate, mounting hardware, pedal assembly, .750" clutch master kit ,.625" front brake master kit , .700" rear brake master kit . (kits include a selection of different size reservoirs ) These master cylinder bore sizes are correct with the OEM ATE or Dunlop calipers. The balance bar that is a part of the pedal assembly allows bias adjustment to get the optimum front/ rear distribution.  For more info please go to: paulspruell.com 

Plumbing. Race fabrication shops usually have the necessary brake plumbing supplies on hand to do the relatively simple plumbing connecting the hydraulics.  The creative racer can get most of it at a NAPA store.   SORRY-WE DO NOT OFFER A PLUMBING KIT Now because of poor quality fittings (China).

Aftermarket calipers. With different brake calipers, you may need different size masters. You can calculate the sizes using the chart posted under brakes (See additional Product Information section). You are welcome to specify different sizes at no additional cost.   

Compact upgrade.   The Tilton master cylinders quoted are the longer 74 series. The shorter/lighter 75 series kits can be substituted.  Price: an additional $72.

Bias adjuster.  For the street the bias bar set in neutral is usually perfect and any adjustment is a one tine thing.  For the  racer, we recommend the optional driver operated remote. This way, small changes can be explored in test sessions without crawling under the dash to change the bias bar. Also, the driver can make an adjustment on course when conditions change. You can choose from the 72-501 basic model or the 72-408 upgrade model with billet aluminum housing.
