Weight reduction !!

I want to start a new topic that is not commonly discussed when it comes to A/CLA/GLAs in any of the forums ive visited... weight reduction. Performance wise you either get more power (tune,turbos,pipes) or lose some weight. GLA45 is semi hefty when compared to similar competitors GolfR,FocusRS,S3RS ect... so i can see some benefits to losing some weight.

Moderns cars are pretty complicated so I imagine there are systems you cannot disconnect without the dash lighting up like a xmas tree.
Those that have gone aftermarket pipes, did you get a chance to weigh the difference between the OEM and aftermarket?

Thoughts? lets discuss

Girodisk.com rotors 8lbs in front per side savings.
brondex 200cel down pipe 7lbs savings.

No sunroof too, the most hated feature to me personally.

Weight reduction is always a great subject...I am a very big Colin Chapman fan as he understood weight (sprung and un-sprung) as the key to performance. My wife and I owned 2 of these and this is a beautiful example of the Chapman philosophy



Now to the GLA weight reduction...unless you go hard core (striping out seats, A/C, stereo, carbon fiber body pieces etc) I feel minimal wight reduction can be obtained. Probably the most noticeable reduction can be had in the suspension/brake and wheel area. None would be cheap and you would have to consider $/lb reduced (vs $/hp & t gained).

Yea love them especially ones with the B series engine.

Thanks for sharing Caug, learned lots of new aftermarket brands today. why brondex? dont like the smell of a straight pipe or does it actually pass inspection in MA?

brondex was the least $$ with 200 cel. i think.
check engine was not suppose to come on , but it did.
so i installed spacer that fixed the light. took me 4 different ones, but i finally got the right one that had 3 attachments and one of them works, thanks god.
Mass is a pain.

Does anyone might know what would happens if i remove that ACO start and stop battery and leave the terminals not connected, just wrap them with electrical tape for the weight reduction purposes?
thanks,C

caug... I think you are going into uncharted territory, BUT I would give you a good bet that on-board control modules would go nuts if one messes with the ACO and delete battery. IMO anyway
