You have a very early EURO engine!! These rods are very heavy!!
They are the same as the 1984 190E 2.3 engine!!
Never have seen a rod failure!!
The newer style rods will take all of the pressure that these rods will & they weigh a bunch less. However the later engines guide the rod from the piston & this can be a problem on aftermarket pistons!
Don't WASTE time & money where it isn't needed!!
Even on the EARLY German touring cars they used stock rods!!
ALL of the pressure is on the down stroke so the bolt only has to keep the caps on.
ARP bolts are good but no better than the OE bolts that came on the rods. Mercedes was one of the first companies that used STRETCH bolt technology & they do work well.
