Hi all, thinking the other day, my subframe paint on my 33 is looking a bit ordinary, flaking off etc.. So, i have to obviously sandblast it, and rather than pay a hundred bucks or more for a good respray, why not galvanise it? would cost me about 60 bucks, never come off, make cleaning easy, and be different.

And while im at it why not do front crossmember too?

Only consideration is id need to hardness test the metal to check its not a high carbon material (unless someone knows?) because it will be heated to about 700 degrees and that will damage or soften some metals.

Anyone got some input?

Im not too worried about deformation, its a pretty solid structure, more so in denaturing the metal and softening it. ill test it soon for hardness. Powdercoating wont get inside properly and will be expensive. all else failing ill respray it myself, just like the idea of gal.. might be onto a good thing biggrin.gif

Or it might be a total failure... ill try source a second cradle so if i screw it, it wont matter

if you're talking about hot dip galvanizing then no way.

You have a chance of warping or worse from the heat if it's not done properly, plus it will add a lot more weight than just powdercoating, as your basically covering the whole thing with a thick layer of zinc.

I used to work in hot dip galvanzing a long time ago, and there is no way i would ever put anything of my car through the acid/hot dip/quick cool process.

Yeah i know its not ideal for a structure like it, but iv sent alot of even lighter things down and got done.. and it would add a couple of kgs... it was just a thought, i can get the blokes to do it a special way if need be and slow cool

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
