New M4 Front Blocks

[MHeadling]

Iv just got the new M4 front blocks, part no U3556 to fit on the Cat

I have bought a M4 tap, now my question is:

Can I be lazy and whip out the diff and drill and tap the bulk heads on the car?

Or is it better to take the bulk heads out and drill them on my pillar drill?

With me feeling lazy, I like the look of option one but I don't want to cock it up as te Petit isn't far away now!!

Opinions please!

I think you know the answer - stop being lazy! Whip them out, you've got to tap them square too afterwards, so will be much easier to do a good job with them out. You've got the pillar drill, - use it would be my advice, don't take any chances when you don't have to.

Once you're done, post up a pic. I did mine a while back drilling standard blocks, bulkheads and not forgetting the spacer shims. Do schumacher include screws and shims with the blocks now? I'm also wondering if there's additional material around the M4 hole.

Well mission accomplished! They are really beefy! Best £11 quid I have spent on the car, I have put the stegger brace on it so it should be tough as houses now!

Yes they do come with some nice Gold M4 shims and some M4x10 bolts, and they have extra material over the standard one, I can't see many people busting these!

I will take a pic tommorow and post it up.

will be interested in seeing these as i have a costello brace on mine and am running counter sink screws with the purple caps for additonal strenth

[fido-dido]

do people recon there is need for both the stegger brace and 4mm bolts?

Or would just the brace or just the 4mm bolts do the job?

no need for both, we run a brace and its fine.
