Ohh, speedo check, flat ground 100kph indicated, cruise locked, speed sampled on iPhone using GPS.
Factory (worn) 205's 92-93 kph
New 215's 95-96 kph
Some would be due to work tyres vs new, some due to larger size, but either way it's still on the correct side obviously.
I couldn't wait that long, noise was just ridiculous for a new car. Perhaps Mitsubishi should realise, that by doing the same as we have, they could increase market share.
Reduced price and quieter more refined ride must add up to more sales!!. Can't compare speedo reading, as I hadn't checked it before but lucky me
now at 100kph on speedo, GPS is 99kph, couldn't be better. I believe economy, rather than improve actually gets worse, according to tyre dealer who swapped mine. Not worried.
I have added sound proofing to under body, boot and engine room, so now able to converse in whispers at highway speeds. next will tackle wheel wells then doors then interior floor,
and fire wall. Will leave roof at this time, may be carbon fiber vinyl wrap will help?
Car which is quieter than BMW in some situations, will by then be an improvement for BMW to follow!!!!!
Will post details and photos when complete. As sound proofing was started a few days more than a year ago it could be awhile.
Can easily get almost absolute silent ride now, by doing nothing else to the car. Just remove my hearing aids!!!! Hahaha
