UUC - 'Big Boy' Clutch Stop - Z3 2.3/2.5
In a car with a manual transmission, the clutch pedal usually has a lot of travel. One reason for the large pedal travel range is to allow novice manual transmission drivers learn the foot-foot coordination between the clutch pedal and gas pedal. Learning the engagement point takes time, experience, and a little skill.

When a clutch pedal is depressed, it releases (or disengages) the pressure plate from the clutch assembly, allowing for gear changes. Timing is critical since not enough throttle when the clutch engages can cause the car to "bog" (or stall) and too much throttle can actually start to damage the clutch if not fully engaged. The illustration shows the start and ending point of a clutch pedal as it is being depressed.

There is a point when the clutch pedal is being released where the clutch will engage. This is the point where applying the throttle is ideal. After many, many gear shifts, it becomes easier and easier with experience to "catch" this engagement point. However, when people drive cars with different clutch engagement points, it's very easy to stall the car initially. Keen drivers will quickly adapt to the new engagement point and remember it.

As a driving style becomes more "spirited", the hand-foot-foot coordination must become more intense as gear lever change frequency increases as does the rate at which the clutch pedal and gas pedal are depressed. If one were to get overly excited, a gear could be missed because of a miss-timed clutch engagement (also known as "blowing a shift").

The advent of an adjustable clutch stop lets the driver specifically set the ideal point of reference where the clutch pedal stops just after the clutch mechanism disengages. Therefore, once set properly, the gas pedal may be applied immediately after the clutch pedal is released.

This lets the driver shift with one less item to worry about, actually forcing them to become smoother. The clutch stop works on all BMWs. Additional benefit is gained when pairing the clutch stop with a UUC Motorwerks Ultimate Short Shifter!

UUC Transmission Mount Bushings - Z3 2.3/2.5
Option 2 - street cars that see heavy track use, dedicated track cars:

Red urethane isolated transmission mount bushings, which are replacing our previous-style red neoprene. These are fully isolated, having two seperate mounting bolt hardware pieces embedded in the material just like the black neoprene and OE BMW bushings. The urethane is a higher durometer (stiffer) material than the neoprene and offers nearly the same drivetrain motion control as a solid delrin or aluminum mount, but with significant vibration isolation. That last detail makes it a better choice for a track car that is occassionally street-driven, where cabin noise is a concern. While UUC does expect some vibration transmitted into the cabin, initial user reports say that it is minimal and certainly acceptable.. Transmission mount enforcer cups not required.

Forge Upgraded Air To Air Intercooler - MCS (<2007)

£494.81

After a comprehensive development program involving thorough testing in various environments we are convinced that you will not find a superior Intercooler for this application.

Our development program included the use of many types of Intercooler core and end tank designs. At the initial stages we ran two development projects alongside each other, one an air to air Intercooler and the other an air to water Chargecooler system. The air to air development achieved significantly improved temperature reductions in comparison, which convinced us to solely concentrate on this option. At each stage of development testing was conducted using a vehicle in various states of tune. (With and without, performance software, supercharger reduction pulleys, bonnet scoops and performance air intake systems.)

With this Intercooler offering up to a 29% reduction over the original equipment it is a must for those wishing to increase engine power.
