Uber Light Weight Stripped Mx5 Worth It?

Hi all,

I have seen a few threads around where the mx5 has been completly stripped out with very little interior etc, I am just wondering what sort of gains for acceleration and handling there was doing that to the car, I may do something like that but maybe not as crazy as doing things like removing the inner door skins or removing all the dash lol.

I know that there will be a performance increase with making the car lighter, I know that the mark 1 is pretty light - then they added more weight over the years and had to fit more powerful engines to cope with this, the mark 1 already weighs less than 950kgs so im just wondering how much of a difference it would make.

Also I am guessing it might hurt the resale value lol

Things like chopping out bits of metal, such as inner door skins and the rear parcel shelf etc will harm resale. Just removing parts you can put back wont, aslong as it all goes back together properly.

I would suggest stripping the carpets and door cards and seeing if you can live with the noise, bumps, rattles etc you will hear. Also transmission tunnel gets rather warm!

Im not sure exactly how the acceleration and handling are affect, if you will notice a difference unless you go very extreme. It will help though, less weight transfer under braking, less car to stop, not as much body roll etc. You need to light weight the front really as the rear needs some to keep the traction and keep the car balanced.

Thanks for the input, im just wondering how much difference it would make as the cars are already quite light already lol im lucky with mine as it doesn't have air con as I know thats a fair weight! This will be my second car ie non daily, so im not too worried about the day to day driving, I currently have an RX7 which I will be selling and getting an MX5 as part ex (plus other bits) my RX7 is too nice to do anything massive to and a bit too rare these days in the condition its in so I figure I might as well go back to an MX5 (Had a mark 1 1.6 before) as they are common and so if the whole interior gets binned/removed its no massive loss due to the high number of cars still left.

Ive heard people have gotten down to about 700kg. If I remember rightly.
I need to get more out of mine and weigh it aswell.

Yeah that was my thinking. If i need to put it back to standard I can source the required bits.

Id guess from removing pas seat, carpet, sound deadening, parts of the dash, changed the boot and taken out some bits from the front Ive lost around 50-60kg. SO I should be about 900kg. Its still my daily and I have more planned, looking to go racing possibly.

Have a look at Scho's progress thread, his is pretty stripped if I remember rightly.

You probably aren't. Look at how stripped my silver one is - it's never made 900kg on the scales (yet). Isn't yours a Mk2? If so it's real wet weight was probably nearer 1100kg before you started stripping it.

If it's for use on the road don't strip it......the noise and discomfort are barely tolerable.
If it's for track use strip it......every kilo you get out of it will enhance cornering speeds and braking distances..... and you will completely forget about noise and discomfort!.

Or indeed go deaf and not hear you have removed the sound deadening

lol im still deciding what I want to do or if I will be keeping the car long term, I was ment to sell the rx7 outright so that I didn't have another car to tax,mot and insure each year lol the car has coilovers, chassis braces and an exhaust as well as a roll hoop I am getting fitted soon, which are all declared on the insurance, the rest is standard. I think I might give it a clean up and check everything over, then go on a cheap track day (oxymoron but worth a go) and see if I enjoy it, then I can decide if I want to carry on with the car or sell it as is with the few nice upgrades ive done on it. The car is solid and has had welded done to it already so I shouldn't have an issue with rust.

Also, you don't necessarily lose the value of a car if you do things properly. If you chop things out and bodge it then yes, but if you properly prepare it for the track the value will probably increase if anything.

I sold my silver one for around ÂŁ3k* - stripped out and ready for the track. As standard it was worth about ÂŁ1500?

* I later bought it back.

Ah ok, thats true, I am planning on doing things properly and not just hack at it with a hacksaw lol I guess whenever I do decide to sell it im sure there will be someone out there who is after the same sort of thing and doesn't want to go through the work of taking it all apart lol

I think the standard mark 1 1.6s go for as little as a grand at the moment, but mine has a hard top which seem to easily go for ÂŁ300, might think about removing the roof out the car and just run with the hard top only which will save on a lot of weight lol
