15W-50 might not be good for cruising at normal 100 degree oil temps, which is what the car is still mainly be used for. Motul 300V is fully synthetic ester oil, and they recommend the 5W-40 for track use. Will see how it does.KP wrote:For track use i would likely go for a 50 wieght oil as under temp it will be much better, and go for fully synth as well motul and a few other companies do it like silkolene?
Also if you are getting lighter alloy wheels why not just fit the track tyres to them for when you do go to the track and junk the spare wheel and carrier and jack and use the tyre rapier foams or your Car rescue membership if you have one??
You could also remove the rear window wiper and motor and use a blanking grommet to save a kg or 2?
At one point I actually considered getting the standard 15" wheels from Mk1 C5 for track use, as they weigh under 5kg a piece. But I'm way too lazy to make changes to the car every time I go to the track. And that would be a bit like missing the whole point of the Activa... you can use it to haul the family from A to B rather comfortably, and blast around corners like your rear end is on fire.
Spare wheel would be an easy diet, but the foams don't do any good if the wheel totally bursts. My insurance covers tow service (not sure if puncture qualifies as a breakdown/accident though), but with a spare I can continue to where ever I'm going. Still, those light C5 wheels got me thinking that I could replace the spare with a lighter one...
About the rear window wiper & motor... already gone. And the 7kg Odyssey PC680MJ drycell battery arrived on Monday. 8) I'm putting it in the place of the original battery (which is almost 20kg) for now, but the plan is to move it under the passenger seat at some point.
Yeah, I'm totally losing it.
