Hi guys,

I'll start of by saying I'm no professional, really I'm doing this just to improve my solid works skills and hopefully end up with a replacement set of centre caps I can use. But I am planning on 3D printing a set of Ray's centre caps to fit lmgt 2's ( may fit 1's aswell?) as anyone with the caps know the plastic gets brittle and the mounting tabs snap off! I have seen sets go for over $600 in good condition... But really they are still 20 years old . All going well the final product will be made of abs plastic ( unless anyone has an opinion for otherwise?) yet to see wether there will be the ability to colour match to the originals otherwise more than likely black , cost I am unsure of yet.... I was going to see if there is any interest first so I could enquire for x amount of caps and see what happens but hoping around half the cost. All the dimensions and measurements are being taken from a genuine centre cap and I will get a mock cap made up first to ensure fit.

Is this something anyone/ones would be interested in? Nothing final just a gauge of interest at this stage.

Thanks!

As Ravi alluded to, I think that the hexagonal caps of the LMGT1, LMGT2, LMGT3 and Magnesium LMGT4 are the same; (but not the LMGT4 GT500).

Pete - aka PLYNX on SAU - has made them before.

They can be either be black or sliver-frost in colour.

 

just need to get the bottom section with the mounting tabs sorted (probably finish it tomorrow night or tuesday) 

but overall it matches the centre cap i have here quite precisely so hopefully this week i can look into getting a prototype printed! if anyone here knows somebody or a company to go through to get them printed please let me know :)

thanks

so.... if anyone is still interested the cap is done!.....well the file at least,  the mounting tabs were a pain but hopefully they work properly ( they are the same dimensions as originals so they should). Now to find someone to print it.

i have spoken to a few company's, the one that seems to stand above the rest is Solid Concepts, they have a base here in WA and also Singapore. They have answered everything I have annoying asked them and understand the use/purpose to ensure that if this does go forward the product is more than up for the task and the finish is on par if not better than the originals. the 2 options i have been given are;

1. SLS nylon production- makes very low quantities viable  but isn't the best suited to the job, it's only available in white ( so will require painting) and the final product is from a 3D printer as such the finish straight from the machine may need sanding/ tidying up.

2. vacuum casting, firstly a set of master copies will be printed sanded/ cleaned/ finished before being used to make a silicone mould from which the final PP/ABS pieces will be made. the advantages being a completely finished cap ready to install with a professional finish quality and available in different colours ( probably matte black to resemble the orginals?). the downsides being the initial cost to produce the mould, to make less than 20 units the cost just is not worth it.... so on to that.

COST; really option 2 is the best option and the one i'm hoping to get enough support for to go with, at 20 units the price would be $80-90 a piece or $320-360 a set. I know this isn't cheap for a set of "fakes" but quality wise I am confident it would at least equal the originals ( likely better), I don't stand to make any money on the caps so it's not that there is a mark up on anything... its simply not cheap to create these low number runs. The mould can potentially be used for 20 sets (80 units) until they expect it to degrade so if there is enough interest (10+ sets) we could expect prices to drop $10-15 a piece but finding that many interested people may be difficult so if you do know somebody please let them know! 

I am happy to do a production run with 5 people ( 20 units) but can't justify it for any less than that, so please let me know if you are interested still and i can get a definitive quote and get the ball rolling :)

thanks guy and if you have any questions feel free to ask

As you can probably see the interest since pricing went up was well... less than great. But ohh well that happens. I did get a prototype printed though just to see how well I did recreate the part and I am very happy with how close to original it is :) if anyone does want the file please just pm me just keep me in mind if you do find a cheap way to get these made!
Thanks guys bcfc43d0d91ea8068d00845f8bf799a3.jpg2e9b2d4c86b0d2f113a39bf878b81545.jpga8a3628a7d6c603349007ca3522cb6dd.jpg7070c82cd6bc66f431df29c1ead1226b.jpg

    • Hi, does anyone know how I can, or can a moderator remove this advertisement please.  Has been sold a long time ago and would like to remove references. Thanks. 
    • There are adaptors that allow you to delete the booster and use an s15 clutch master cylinder.    if you want to keep the booster they are still available brand new 
    • I visited again today: It would appear they have painted the main body of the car and some parts of some of the panels, so I can say that I now have BMW parts in my car, much to the envy of @Dose Pipe Sutututu It is still covered in dust which is quite the tease but I did look at a few circumspect spots that will be behind bumpers and such and wiped some dust away: After my repeated begging to PLEASE DONT PAINT OVER THE ENGINEERING CERTIFICATE (you have to re-engineer the entire car if they do) I see THIS: Which is great. Excellent job tbh at least to me. A better non dusty example would be the backs of the doors that have been painted: Giving a reasonable contrast between old and new (I know the old isn't clear coated on the inside of doors). The door card will well and truly cover where the old paint is, you can see in the second pic some of the black butyl/whatever shit is sticking the plastic sheet behind the door transfer that has happened since it's clearly been stuck back on. The most maddening thing about this colour is every time I saw it in the wild it looks like another colour, same with photos of many cars with the same colour looking wildly different in every photo anybody ever takes and this is no exception. But stand a little further back and it suddenly looks dark AF. I did tell them when I was discussing which of the 70 million charcoal colours to choose from (a porsche one, a BMW one, or a R32 GTR one etc) that if they just ignored me and chose one at random I would probably never notice. Maybe they did. But the colour is supposed to be B39 (BMW Mineral Gray). Boring I know, but the R34 sedan (to me) really shows off it's boat-ness when you paint it in a bright colour like bayside blue or white or whatever else. I do have a fondness for AR2 Nissan Red, but decided against that because it'll have pretty odd contrast to random bits unpainted (like engine bay, bits of trim etc, and maybe it'll fade). And people will always fkin comment on AR2. Everything remains super dusty. I have tracking numbers for the new heads, as well as some Improved Racing goodies, but they probably will be a next year thing by the time they end up on the car. I did some maths on the heads and I know why nobody goes to this extent in Australia, because it's really not worth it, given I could have just CNC'ed my current heads, bought a FAST102/TB and used my current rocker/spring/cam combination and get a 383 stroker (or stroked a 6.0 GenIV bottom end to 6.6L) built for the same price of just the setup in the mail/on the floor here. Or I could have bought a LS3 and a Drysump system. And then have a complete engine to sell. Oh well
    • We just disconnected the vacuum line if I remember correctly, booster is still there. Is there a rebuild solution for the booster or a different adapter that will work for GTR chassis?
    • Yeah 4wd (boosted) has a recess in the firewall for the booster, and 2wd is flat - the example in the link shows the flat surface. When you deleted the booster, did you just attach the factory slave cylinder directly to the recess in the firewall with no adaption?
