Julian H Posted August 20, 2015 Share Posted August 20, 2015 OK, so tonight was not so successful for me!+ Removed one horn 293g saving+ Fitted new front section of boot floor 479g saving as reported previously+ Fitted one of Carstens lovely handbrake grips, a 42g saving compared to the CC Ali jobbie- Tried to remove rear section of boot floor to weigh it and assess replacements. OK, so I am not the brightest spark but how do you get it out . I cant see even removing the rollbar would make it any more possible.- Tried to remove my seat. The bolt just rotates. How do you stop that, I can barely get my finger into the top side of the bolt [?] let alone a spanner! I want to remove it to see if I can get one of my suppliers to make up fixed brackets in lieu of the runner. I understand the runners weigh in at 1.6kg per set on the spreadsheet. I can get something made up which will weigh much less than that. Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted August 20, 2015 Member Share Posted August 20, 2015 - Tried to remove rear section of boot floor to weigh it and assess replacements. OK, so I am not the brightest spark but how do you get it out . I cant see even removing the rollbar woulf make it any more possible. Just keep wiggling with confidence. Have you tried going diagonal... in two different ways at once?- Tried to remove my seat. The bolt just rotates.

But I'd cut a slot in the end of the bolt with a cutting disc in a Dremel, and then hold it with a screwdriver while you bring the nut down.Jonathan Link to comment Share on other sites More sharing options...
LawrenceR Posted August 20, 2015 Author Share Posted August 20, 2015 One way to remove the seat is to cut a slot in the end of the bolt that extends through the nut, under the car. This can be stopped from rotating with a screw driver whilst you unbolt. Link to comment Share on other sites More sharing options...
Julian H Posted August 20, 2015 Share Posted August 20, 2015 Thanks for the info, will look again at the weekend. I like the slot idea Lawrence, I am pleased there is no mark on your scuttle, I think it looks much nicer without the trim. 6.66kg, well done. This is fun isnt it!JK, I think the boot floor challenge should be on Krypton Factor. No matter which way I tilted, rotated, raised, lowered etc.. I couldnt get it out. All the time making sure I didnt damage the Ali bodywork from the inside! Link to comment Share on other sites More sharing options...

SM25T Posted August 21, 2015 Share Posted August 21, 2015 The boot floor contortionism certainly works on an SV. Left side down, tilt front edge upwards, right side up with left side pressed into the sideskin under the top chassis rail just rearward of the suspension tower.

LawrenceR Posted August 22, 2015 Author Share Posted August 22, 2015 "This is fun isn't it"Yes, in part I bought my car as it a hobby. Building it was great and I just see this as an extension of that. A bag of nylon M5 bolts arrived today, I am going to see how much can be saved by replacing those that hold the rear wings on. Furthermore it should, help protect the side skins if I ever hit anything with them.In addition, having taken the wedges from the fog/reversing lights it look as if their bolts can be replaced too.

LawrenceR Posted August 22, 2015 Author Share Posted August 22, 2015 RH rear wheel arch now secured with nylon nuts and bolts 0.068 kg saved cost £2.50 ishI will do the left when I have a bit of time and it is not beginning to rain! My legs were hanging out of the garage. Link to comment Share on other sites More sharing options...
Julian H Posted August 23, 2015 Share Posted August 23, 2015 Every little helps! On Friday evening when I was in my Seven I noticed the length of the bolts which fix the mirrors to the Aeroscreen and thought maybe I should replace them with shorter ones. I would love to build my own Seven too, and do all this from scratch. Trouble is how expensive the kits are these days! Link to comment Share on other sites More sharing options...
LawrenceR Posted August 23, 2015 Author Share Posted August 23, 2015 Or will nylon be strong enough? Link to comment Share on other sites More sharing options...
Julian H Posted August 23, 2015 Share Posted August 23, 2015 I'd keep an eye on them if I were you.i am still looking for a new material for my rear boot floor. I found something called Dufaylite ultraboard Polyprop that looks interesting. Can't find the weight for it but suspect it is quite light. If I find it is, I will ask for a sample.

LawrenceR Posted August 23, 2015 Author Share Posted August 23, 2015 I guess the piece of ply was flammable, unless treated. Link to comment Share on other sites More sharing options...
Julian H Posted August 24, 2015 Share Posted August 24, 2015 I think it is Ali for motorsport use, I notice its an Acadamy regulation, they mention something along the lines the floor should not be replaced by CF. Reading into that, they seem to concede that replacing with CF is a done thing?I finally got the rear boot floor panel out. I have not a clue how, it just seemed to come out all of a sudden. I hope it won't take me as long to figure out how to put it back in. First job, to weigh it. It is 1.89kg which is approximately 6.3kg/sm. What thickness CF would I need to span the approx 330mm between supports, be adequately strong to do the job and fix the filler neck cover too? I don't mind a little flex in it. I never put much in the boot, perhaps a hood and my manbag Cheers,ps - Lawrence, just got what you meant by nylon being strong enough... not sure I could handle the appearance if I am honest. I think I will just replace the mirror fixing bolts with shorter ones. Link to comment Share on other sites More sharing options...

LawrenceR Posted August 24, 2015 Author Share Posted August 24, 2015 Julian, I know what you mean but I think I could live with black ones.http://www.ebay.co.uk/itm/25-Nylon-Plastic-BLACK-M5-Bolt-Screw-COUNTERSUNK-PHILLIPS-12-16-20-25-or-30mm-/291243188837?var=&hash=item43cf726265now I just need to find what size is needed.

Julian H Posted August 24, 2015 Share Posted August 24, 2015 Oh, black, now your talking! I like that! Can you put threadlock on nylon?I made up a rear boot floor with the [fire retardant] Armaboard 1440gsm material that I made the front piece with. Its more stable than I thought but don't think it will be suitable even though its only 415g, close to 1.5 kg saving. I will put it in place and for a few weeks and see how I get on. I also considered cutting loads of holes in the standard ali floor and covering them as another option. Probably end up with CF though.No video JK, I needed both hands available for this one!

LawrenceR Posted August 27, 2015 Author Share Posted August 27, 2015 I have just made a less economical weight saving purchase than you Julian!I changed the blots that hold the interchangeable aero screen on from steel to titanium.Two bolts £3 each, giving 3g saving per bolt. Total saving 6g @ £1/1g.This is getting silly! Fun but silly.I should be able to improve on this a bit however, the bolts I have bought are m8x30. At most they need to be 20mm long so I will shorten them when I get the chance.Is a bench grinder the easier option? Or does any one know where m8x30 are needed, in a low stress operation, are on the car? Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted August 27, 2015 Member Share Posted August 27, 2015 I'd recommnd reading about cutting titanium before you reach for the tool. ;-)Jonathan Link to comment Share on other sites More sharing options...
