A lot of former FSAE guys on here. Good to see. I was part of the ADFA team last year and after a change of uni im now part of Redback Racing with UNSW. Below is a pic of our body work from last year, im in charge of the bodywork/composites this year so hopefully ill learn a fair bit about that side of things.

I've got a quick question about working with CF. I've got some carbon doors and guards, but the top 3-4" are painted in grey. I want to get them sanded back to all CF but i'm not sure whether i trust a normal fibreglass workshop. Would the doors need to be re-gel coated or maybe just another clear coat on top? It hasn't been gel coated over the painted section (you can run your fingernail up the CF part and sort of get your nail under the painted section).

HI neil, im not quite sure what exactly ur asking, because as far as i know, gel coats are used on moulds to get a bit more bling on ur part, so id say its a coat of clear that ud be after. If your going to sand back to the carbon you will have to go with a coat of clear. Might be a good idea to try a little section first and see how you go. out of curiosity id love to know what the weight diff is between the composite door and the standard metal..

Yeah that's what i was trying to get at, if i sanded back the paint would it just need clear coats, not a gel coat.

I'll weigh the doors when i swap them this weekend. I already weighed the guards which were 1290g, GTR aluminium ones were 1900g (i guess gtst steel would be a kg or more heavier?). The bonnet isn't as light as the last dry CF one i had because its got a lot more ribbing.

Vortex Generators.

1. They rock.

2. They look tops

3. Why should the Evos only get them?

4. I know 10 people who would buy them.

Its the bit on the top of the rear window

Just wondering if uve ever seen them without that strip of paint? If i had a shmick carbon door i would not paint over it.... maybe that portion of the weave was not as crash hot? Anyway go for it, just be ware to do it very carefully once u get to the carbon. Probably a flat pneumatic sander with some 600 wet or dry to start with . once ur down to carbon go to 1200 wet/ then 2000 wet (if u want) followed by ur coat of clear.

also we made a set of doors for an s15 they weigh 6kg. original weight is 38kg i'd say thats a big saving.

and neil i'd watch rubbing back to the carbon, its easy to rub through. once you rub through the first layer it changes its look, maybe you should just paint the tops the same colour as the car leave the bottom bit carbon finish.

Ahh yes id say thats a weight saving alright...Massive one.. Just wondering what other carbon bits u make? i Guess u guys use pre-preg with autoclave cures?

We make pretty much anything... :D mostly motorsport parts.

We dont use pre-preg or auto claves... we hand lay everything, and vaccum infuse everything...

Hi MrVspec, if you don't auto clave the parts, am I correct in assuming that you don't do stressed stuff such as prop shafts?

Cheers

PS your parts look very well made... you NEED to get your website up again! :D

PPS can you do an R32gtr with Z-tune style louvres down the middle?

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
