shaving 256mm brakes

I don't understand why though? They wouldn't take a grinder to a con-rod to make it lighter/fit, yet thats has no detrimental effect on crashing.

They can't get to a con-rod though ;) Brake calipers are nice and accessible behind rimz innit.
People need to realise that even brake calipers have a finite strength. They are designed to carry out a purpose for a set length of time with set operating conditions. By the time most people get their hands on their super duper ATE brake upgrade, that design life is probably near its end. To then remove material from the highest stressed area of the caliper is STUPID.

you see you say that but vauxhall made novas with funk more material than any of us have got, especially you oli. think of shaving your calipers as weight saving lol

I hear what you are saying and know where you come from. I'm no bodger - I see running spacers as just as bad as it's outside of Vauxhall's original specifications for the hubs and bearings.

Which area are you referring to? Mine isn't shaved across the back section of the 'clamp' part of the caliper.

I bought mine new to avoid the second hand gamble.

Please don't take this the wrong way as I'm mearly illustrating a point here:

Didn't your tie rods goose your front panel and cause a serious safety issue? So you have infact run something that is potentially dangerous? Because the design hadn't been entirely thought through?

My point was that if you do something right and understand what the consequences could be then you will be fine. I appreciate common sense is long dead in this country but meh.

I get your point about the weakness of the caliper after, BUT i have done the large trim on my calipers for my 3 spokes, i know it makes a weakness right on the corner but that is where all the stregh is there is so much metal there and theres so little compared acutaly inline with the disc, i havnt even touched that bit.

Never heard that one :wtf:

Brand new discs and pads, with new pads each time is the only way for me.

The highest stressed area of a pin-sliding caliper is the fist portion, and ultimately the area where the fist curves from the horizontal disc spanning portion to the vertical for the pad backing.

One thing that is been forgotten here is that this car is only a 1200,would Gte brakes suffice? Its hardly going to be stopping from high speeds is it
