And why not? They're as good as any of the others, hb, and don't let anyone tell you otherwise 😉

Can you post a pic up of the subframe when you've coated it in the Dinitrol? I'm after all the protection I can muster (especially on the rear - I'll let the oil leaks get to work on the front one :D).

well i guess the weight of the leather trim, high gears and all the other heavy trim limits the competivness a little. Are there even any classes where you could enter one?

I did the first coat today, the thin 3125 stuff, this creeps into all the gaps between seams and seals them up. I'll take some photos before and after i do the top coat of thick stuff.

don't forget if you are going to race the car to weld a four millimeter plate where the bump stop hits the top arm as works race cars did to stop to much lift on the front wheels:cool:

Blimey - three and a half years since I started the subframe project and I've finally got an engine sat on it!
Don't get too excited mind - this is only to offer up to the shell so that I can work out where to cut the holes for the heater pipework.
I did need to grind back a couple of the welds around the engine mounts though, to get the engine to slide in:

And here it is in situ:

Is there an easy method of getting the pots back into the diff housing?

Do I need to take the pots off and offer them up separately?

Don't make matters worse Pad, by asking Graham about his gusset strengthening 😀

Did you enlarge the holes in the subframe so you can get the pot joints in and out easily - if you havent it might be a good idea , makes life sooo much easier in the paddock

They're not clinkers - all my welds look like that :p

pad - no I didn't enlarge the hole. It's not like I'm planning on changing driveshafts too often (but yes I did realise quite early on that larger holes would make life easier).

I gather the general idea is to hit the hub end with a rubber mallet (trying hard to miss your fingers) to overcome the annular ring, yes?

it just makes life so much easier to pull the whole drive shaft out if you need to get at it in a hurry - caliper off , ball joint bolts, track rod end bolt and the whole hub n shaft can just come out - its a speed thing really , one of those little pot joint splitters seem to be usefulll
