New brace bars, saved 2.1kg

Cant believe your car was that light and still had head lining and the rear quarter sound deadening.. thought they'd already gone! Just makes my car seam heavier in my head :/

Quick update,

Had the day off work and wife's on holiday so I managed a few hours in the garage.

Plan is to get the car strip to a bare shell ready for its new weld in roll cage. I've booked in for a Historic cage, but tied into the A & B Pillers. Will also link into the rear turrets.



So today I've been removing some more weight







Cut out the roof lining bars support.

Blimy some serious work there

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

Stripped shell ready for its new Rollcage.

Bare Shell weighs 109kg currently, plan its to weigh it once the cage is done.

Searching is all you need on TurboMinis

Alu/CF Parcel Shelf?

Yep alloy rear shelf is on the cards.

I'm trying to aviod drilling holes everywhere. I don't want it to look obviously that its been extensively lightened, otherwise I'd drill the cross member etc.

I managed to strip the front subframe this afternoon and double check some predicted weighs. I'm now at estimated 504kg and pretty confident another 5kg can be found.

Glad to hear that. Holes look shit

I seriously doubt it!

....and I'm also taking my personnel weight loss quite seriously...

Matt , you no you've gone too far when it looks like this.

Blimey... your 14.5st now?! Well done!! Where are your subframe mounts from? And what make are the hubs? They take the metro balljoints?

Some lovely parts and work there, first time me seeing this thread.

Whilst maybe extreme...

The alloy top arm, has square edges etc. Radiusing these would remove a little material and safe a few grams ?
gun drilling the centre of the big bolt ?

The cast steering arm...

I was extremely bored a couple of years ago when re-doing my Granada front suspension, so took to the "upright" with a flap wheel in the grinder. Only a few minutes work and over 200g removed from each.
I was mainly cleaning up to paint, but decided to weigh before/after too.



Fuel pump looks like an 044 ? I'm sure some lesser pumps would be capable and lighter ?

Not to pollute either, but Ralph went to extremes on his RV8 metro project to reduce weight whilst retaining a good standard appearance, it's worth a read if you havent seen it already.

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

that is some serious unsprung weight savings

you can do anything if you set your mind to it...
i rather blow it up winning than keep it together losing.

finish date set for project 1... march 2018

Ok today I drop my shell off at Owens Fabrication. The idea was to save weight with the T45 weld in cage, however to stiffen the car to improve handling, more T45 bars have been added. So guess what, it's going to weigh more than before. Endaf's advice should mean the increase stiffness will outway any weigh saving in the corners. Not sure how much extra, but possibly another 10kg including miglia bulkhead and extra strength for inner wing supports. Cage will be tied into both the rear turrets and alloy beam aswel as front subframe mounts.

After a chat, I've also concluded the Kirkey seat was possibly the wrong choice. Especially as its now way to big for me. So maybe another 2-3kg to add back on for a carbon / grp racing seat.

So where back to 518kg, I guess sub 500kg is now out if the question. I long as I can personnelly get to 80kg, it will still be sub 600kg including me. Just another 14kg worth of dieting left.

Fair play on the diet dude, I know it's fucking hard work! Trying to get back on mine but burgers are too damn tasty!

You've gone through all this trouble saving weight / crash the 500kg barrier, only to settle for a cage weighing 10kg more and crush your dream because someone tells you so?

Isn't the title of your thread drag strip weight loss? Why wouldn't a like for like cage in T45 be more han sufficient? Why would you need miglia shell stiffness on the straights? (or without running huge slicks on the corners for hat matter)

Again stick to your plan as you're doing a superb job. The personal weight loss is just icing on yhe cake...

Edited by Evoderby on 23rd Dec, 2014.

Ive just fitted the T45 cage and should still be around the 400kg mark. Keep going theres no end of weight in all the little bits to come off

I seriously doubt it!

Double post
