That's right, the Corsa now has 100% more modifications than previously. Before it just had a K&N air filter, but now it has a K&N filter and a strut brace!
Why bother? Well that's a good point, but it was only $5 so I couldn't really refuse. The brace is designed for a Cynos or Starlet, and the Corsa is very similar to these (same basic chassis as a Cynos)
Did I notice any difference? Well not really, perhaps a little bit, but it could all just be in the mind. I'm sure if the car didn't have 175/70R13 tyres and 180,000km old springs/shocks/bushes it might have been more noticable :)
