The B4.2 already comes with the 4th hole included on the tower...

So if my B4.2 has a B4.1 shock tower on it ? (Original one broke before they made the running change) I should add a 4th hole ?

Thanks in advance Cherry.

Even the 4.1 tower has the 4th hole included.
Only the old B4 tower needs drilling for the 4th hole ....

Are you sure? The picture on AE's website show 3 holes per side.

My B4.2 has 3 holes in the rear tower.

Inside hole is the "4th" hole that everyone used to have to drill themselves.

new towers have 3 holes but they moved them in on the tower.

Yes , I'm sure ...
Was one of the first to show how to drill year's ago on the thread ...

I am going to have to disagree neither of 4.2 have 4holes standard unless i misunderstood.

My understanding was they eliminated the outer hole in the mold and added the inside one, so the new inside hole is the 4th hole compared to the old ones

Can't we all just be happy with 3 holes?

Yankeefan is correct. They did a running change and where people used to drill the inside hole is where they put the inside hole on the new tower.

If you are doubtful of whether or not you have the updated tower just buy a new one and remove yours and compare the two...If yours is off just toss it or drill it...

So right quick, about to make a purchase from amain, what pistons should I buy for my B4.2 for an outdoor bumpy large low to medium grip track...? I would like to make tjis my final purvhase and have everything I need, thanks

The pistons included in the kit will be great, 1.6 x2 for front 35w & rear 30W ...

Alrighty, thanks George. I know this isnttheright thread but I'm not getting answer's in them so what about my B44.2 and SC10.2...?

For those who add weight to the front of car, should the weight added in the rear be equal so as to maintain front to rear balance? This doesn't include factoring in the weight of the ballast.
