Preparing the car for a deep interior clean, I decided to remove as many items as possible and purely in the interest of science decided to weigh them all and then take the car for a quick blast on my favourite loop. Surprised the total weight for all items was 53 kg which equates to approx 4% of total weigh based on my 3 door manual car with belvedere wheels.
Stripping the car was easy and took around 10 mins.
Spare wheel 14.3
Rear upper seat main section 15.0
Rear upper seat other 5.8
Seat bench 6.8
Jack and bits 4.4
Boot floor 3.0
Dynaudio 2.3
Parcel shelf 1.3
Driving impressions, a lot more noise was transmitted into the cabin. Car seemed a bit more responsive, especially in 4th gear for some reason. Most noticeable, the ride was more jiggly, presume due to the weight removed from the rear upsetting the standard suspension rates, as the CS is usually super smooth.
Will take it out again for an extended drive later in the week. Definitely worth doing in preparation for a track day.
