Any one know??


I have only seen Porsche 911 and VW rods made like this.
It may balance the rods better, more weight towards the middle and in a flat engine access doesn't matter, you have to remove the cylinders and split the case anyway.

Hi Safe,

It appears screws are fitted from the middle of the rods. I think mespiecesuato gave you news by mail about these rods, no?
From them, estimated weight was about 570g without the screws.

I have not received any emails from mespiecesauto, I have checked the spam-folder too.
Have the rods been test fitted to an engine?

Anyone actually fitted/used these rods yet?

Thinking of a winter project to rebuild my 924 engine and wondering if its worth the hassle to change the rods to these lighter ones since i'll be going for lighter pistons as well.
What are the implications of using these rods?

As I have (on the shelf not in the engine) the "Aliexpress-rods" that are made the same way I think that they can be torqued with a crow-foot but the bolts MAY foul on the lower part of the cylinders. If it does you could probably clearance that.
But it is a series of uncertainties... If you make this mistake with the rod bolts what else?

This seams like reasonably priced rods:

$1200, but Australian dollars I believe at ~60% of an American.
