Alloy wheel weight is very important to the [http://en.wikipedia.org/wiki/Unsprung_weight unsprung weight] of the car.

Stuck on what PCD or Centrebore means, [http://en.wikipedia.org/wiki/Wheel_sizing read here].

If you want different wheels to those listed below, you need pcd converting wheel-spacers like [http://www.eliseparts.com/shop/index.php?main_page=product_info&cPath=165&products_id=219 Hubcentric Wheel Adaptors.] as 4x100pcd is already relatively common.

What you need is simple wheel spacers in 4x100pcd, centre bore 56.6 to make the offset a little more common. These spacers would fit Vauxhall Corsa, Astra F&G, Tigra, Vectra + OPEL Ascona and are therefore pretty easy to come by and quite cheap. [http://www.performancefx.net/wsvauxhall.htm example of cheap spacers]

You can tell which size throttle body you have from the numbers on the top edge:

===48MM Body===

The 48mm Throttle body came standard and can be modified to flow alot better (almost as good as the 52mm) by removing the rubber wedge that is located on the throttle body butterfly

(marked in red on picture below).

Remove Butterfly from the throttle body and take off the rubber wedge then Heat the butterfly up and put it on a ceramic tile, any metal surface may cause the solder to adhere. Use multi core solder and just push the end into the hole so it contacts the parent metal, it should then melt and brim the hole, if it doesn't the butterfly isnt hot enough.

Key the hole and just outside with P180 wet/dry or similar, or a small file.

===52MM Body===

The 52MM Throttle body came standard fittment on the Elise S2 111S (and also included as part of the Lotus drivability kit for the S1 Sport 160).

===Advantages===

"when we exchanged the 48m TB for 52 Item we got a stunning 1 bhp max power increase, we got a 3 Ft Lbs max increase in Torque"

"The Torque curve increased by 4 Ft Lbs Average and at one point on the curve an 11 Ft Lbs increase was recorded. This 11 Lbs increase was quiet low in the rev range."

'''-''' Quoting from SELOC member [http://forums.seloc.org/member.php?action=viewpro&member=The+Gimp THE GIMP] from when he tested the 48mm vs 52mm on a rolling road.

===Fitment===

Fitment is very easy and only takes around 30 minutes to change.

You can tell which size throttle body you have from the numbers on the top edge:
* TV1 = 48mm
* TV5 = 52mm
