It may last longer with a softer right foot, combined with a softer left ( clutch ) foot.

 

did think othat one but then ruin all my fun as all twisties here!

 

All subaru boxes are weak, I think its just a plain fact you have to live with. The only way it seems to get some strength, is to buy uprated gears.

 

well hopefully the p1 will be a bit better! just a matter of changin now!

 

get the gears shot peened,but mask the bores... shouldn't be expensive at all...

 

STI offer a motorsport gearkit which is stronger but you will probably still break 2nd gear. the other option is to move to 4.4 diffs with the new S2 prodrive kit which I beleaive to be more reliable We are about to move to this option on my group N car. The final option is a V5 casing and a RTD dog kit at £4200 + VAT and you won't break it.

 

Drop Mark Aigin a mail. He has been testing an uprated gearbox for a while.
