Hey guys

Its gonna be sort of hard to explain i think as im currently at school so i cant really hook up any cool paint drawings to aid what im trying to say...

but masically i want to know what direction the slots on slotted discs should go and whether it really makes much differences..

I remember reading on this forums that they should go a certain way (which is the way that i have them on my car now) but since then the cars i have seen in magazines / around have got them going the other way...

No. on the drivers side of the car. the inner part of the slot (Closest to centre of wheel) enters the caliper first... (while gonig forward :P )

As in. the top of the disc, when looking at the drivers side. goes like (as opposed to /)

Which way should they go? any disadvantages in going the wrong way?

Cheers for the help. :P

I would expect that as the rotor rotates in it's normal direction, then the bit of slot nearest the centre / hub should enter the caliper first, and the outer end of the slot should enter last. If you were to put a pointer of some sort into the slot, then as the rotor rotates, the pointer would move from the inner to the outer end of the slot.

Viewing the driver's side, with the slot at the top of the rotor, the slot should look like , and the passenger side should look like /.

This orientation allows for hot gasses and other crap to be thrown to the outer edge of the rotor rather than being all bunched up near the hub.

thats exactly how i thought...

though since i have put them on my car. i have seen in japanese mags, and even other cars on teh street. and they are ALL the other way?

like a few pretty nice D1 cars or circuit cars etc built by teams that would probably know whats going on :P and they have them the other way.

Strange.

      I transferred from full time service to Army Reserve, so I still have access, work has been super keen to get me in to work in the OPS realm, so just turning up to use the gym......and ovens, isn't causing any issues, apart from me needing to keep on telling them that I won't be doing any reserve days until I get my joint in Goulburn sorted  Basically I can now work whenever I want, for how long I want now, and it's all tax free Next time we have some fires or floods you might see me covered in mud, or cutting sick in some plant equipment cleaning up, the Reserves love getting in the news, LOL

      Final finish outcome of 80°c was typical to the pics, I've turned the oven down to 50°c and will pick them up after the gym tomorrow  The before and after difference was amazing, the wrinkle paint has covered all of the casting marks completely It did take a couple of hours to key it all and get in all of the crevices, but, for me it was time well spent for the final outcome, but I have all the time in the world to do it at the moment  Ended up with 4 coats, each sprayed at different angles to get optimal coverage and thickness As for the fixtures and intake box thingo that hasn't made it, the supplier is apparently posting the fixtures, and, are now sending a different CAI that is in stock The replacement CAI is actually better than what I originally ordered, but will require a pod filter that locates under the front bar, still serviceable, but it basically removes the whole OEM filter box and ducts into the front bar, so filter cleaning will require ramps and the removal of some front bar undertray, not a war stopper, just some ramps and an additional 10 minutes work every few months From looking at it it is made from alloy pipe from the throttle body, through the CAI hole in the rad support, then right turning under the bar, luckily the wrinkle paint was on special and I got 2 cans for $30ish, so the alloy will get the same wrinkle treatment as the intake manifold, hopefully it turns up soon, either way, the car will be getting booked in soon, if the parts aren't here, I'll just get MX5 Mania to " make it work"

      I'm so glad base security is so high. I see they stopped some random codger from being able to just wander in off the street... 😛   PS, intake looks good!

      Is there a good place to learn how an engine works online?

      By RA708 · Posted

      Exactly how each part works and how they all work together to make the engine function. That's all I'd need to do a basic build. Maybe how forced induction works. I probably need to learn some of the maths behind it all as well.
