WEIGHT MAN­AGE­MENT

Fast Ford - - Ff Tech -

Power-to-weight is key to the ac­cel­er­a­tion of any car. The less weight your en­gine’s power has to move, the faster it will ac­cel­er­ate. While gear­ing and even aero­dy­nam­ics will have an ef­fect, from a rolling start and pro­vid­ing both cars have full trac­tion, two cars of the same power to weight ra­tio will ac­cel­er­ate about as fast as each other – even if one car had 100bhp and the other had 1000bhp en­gine. That’s why su­per­bikes are so fast de­spite hav­ing sig­nif­i­cantly less power than most cars.

So, the sim­ple thing here is to make your car as light as you can, but do it wisely. Many parts of cars weigh very lit­tle but are of­ten re­moved, such as car­pet and rear seats. But many parts are of­ten ig­nored, such as heavy wheels, stan­dard front seats and the sticky un­der-car­pet sound dead­en­ing, all of which add up to a con­sid­er­able amount.

It’s also worth con­sid­er­ing the dis­tri­bu­tion of the car’s weight too. Weight over the driven wheels helps push the tyres into the ground, in­creas­ing trac­tion. This is why FWD drag cars of­ten have as much weight as pos­si­ble at the very front of the car, and the op­po­site is also of­ten true of RWDs. Mov­ing huge amounts of weight around your car isn’t easy on a road car but be mind­ful of this point when adding parts or re­mov­ing parts and you can re­ally make a dif­fer­ence. A good cor­ner-weight setup can see ad­justable coilovers tweaked to move weight around the car slightly too – a neu­tral car will be set the same all round, but rais­ing the rear sus­pen­sion can help push weight of over the front wheels, for ex­am­ple.

Cor­ner weight­ing helps you to con­trol the weight dis­tri­bu­tion of the car
