Some rally style alloy wheels are lighter – (less weight = more speed) and also are designed to increase the cooling of the brake disks.
Some designs hold up better to being curbed than others and some break very easily when hitting a pothole or curb at speed.
Always go for the best quality alloy wheel that you can afford and read the reports and reviews. If you do go for a different overall size you must get the suspension and tracking realigned to avoid uneven wear under acceleration.
Spoiler aerodymics rear spoiler design and construction
We look at how spoilers work? We also explain the difference between a spoiler and a wing. Spoilers are generally closer to the body of the car and help diffuse the air.
Wings are mounted much higher up and have an aerodynamic effect of creating downforce
Cryogenic engine treatments
When putting more power through an engine you need to ensure that every part will perform at its optimum.
One of the motorsports favourite techniques to improve the durability of an engine is a process know as cryogenic treatments.
As you can guess from the use of the word Cryo – it involves the cooling and heating of the engine block to temper the metal changing its structure.
Particulate filters and FAP Performance gains.
The particulate filter is a stand alone unit. It is located upstream of the cat in the exhaust system and its purpose is to remove soot particles from the gas stream. The cat the proceeds to do its usual job of converting CO to CO2 and is in no way dependent or relied upon by the particulate filter.
In diesels the cats are two way devices and run in unregulated mode (ie. no O2 sensor like a petrol car).
