Hi all

Has anyone here attempted to lose some mass off their car?? I'm not talking about ripping seats out or anything drastic but just stuff that you (or re-phrase: the wife ) won't notice visually (i.e ditching the space saver for run flats, stripping out soundproofing etc).

Does anyone think there is an awful lot on offer or would you have to go down the stainless exhaust/carbon panel route.

Many thanks

Darren

if you want to keep the luxuries in your car...lighter parts would be your best bet... and no spare tire :D

You know, this brings up a good question. If I dont have my spare, and I get a flat, would Acura TLC service tow my car somewhere?

If you want to reduce weight, there are couple of "free" things you can do. However, note that everything you do is a sacrifice for luxury and comfort.

Stage 1

Spare Wheel - Replace this with a fix a can instead, this will free up a fair bit of weight in the rear. However not significant enough to feel an acceleration difference, handling may slightly improve depending how well you already know your car to feel the difference.

Rear Seats - This is also heavy, and also the easiest reverse if need be. If you don't have a tenancy to carry passengers, remove this and it'll further reduce more weight. When this is removed, you will start hearing more cabin noise especially from the engine and exhaust.

Stage 2

Panel Trims & Carpetry - Depending on how extreme you take it, I don't believe TSX owners will go so far. Removing this will almost remove all sound insulation as well while saving weight. A harder process to reverse and most definitely not necessary.

Tar / Permanant Insulation - Dry ice is your friend if you want to take it to the extreme and remove all the black bits and pieces Honda put in place to reduce road noise and contact from the road. This is not reversible and will expose the full core metal of the chassis.

Stage 3

Body Panels - Unfortunately there is not much development on this even in Japan, in search of a dry carbon bonnet/boot lid will remove enough weight to improve acceleration and handling. However, this is when it starts getting expensive. Dry carbon reduces weight, not wet carbon.

Bucket Seats - Factory seats are very heavy, especially those ones with plenty of comfort and padding along with electronics and memory. Replace them with full one piece bucket seats will see significant weight reduction as well.

Chassis Reinforcement - Rollcage custom fabrication, for all the weight removed, the chassis now needs to be strengthened. This will no doubt be permanantly and illegal in some states and countries for public road use.

So, as you can see. You can take it from S1 to S2 and to S3. How extreme you want to take it would be a bigger question. I don't believe the majority of TSX owners will take it pass S1.

Yup. Many thanks Noel.

I was having a rethink and the spare is definitely going in favour of run flats. Can't really use the spray can here as garages simply refuse to fix punctures when full of sludge so is the only viable option. The chunky board that doubles as the boot floor can also be replaced by something thinner but will require some work. As will the insulation under the boot lid.

As for the under bonnet insulation this can go too as it'll save a few ounces ;) and more importantly let in a bit more engine noise :D

What I'd really like is a pair of JDM Recaros but I guess these are as rare as rocking horse sh#t.

A titanium header/exhaust would also save about 50% of the stock mass but I've yet to see one of these either :(

Agree totally about taking it past stage 1 though. The ideal scenario would be to get a CF bonnet and boot but these are really expensive options and even more so if you use proper CF.

I do wonder what the JDM model is like though as I have a feeling that it probably has a mass of about 1300kg's (as opposed to our 1400kg's). If I could just the power to weight to about 150/tonne then I'd be happy....

Yes, the JDM model is much lighter. Even the AU model is lighter to begin with, 1300+ as well only.

Those OEM JDM recaros are very heavy, don't be deceived by their looks. And there is no titanium exhaust manifold/header I've ever seen for a Honda for any model, let alone the CL9. You can however get a titanium catback exhaust from Amuse.
