guys... nak tanya sikitla.bolehkah front and rear disc brake di "cross drilled"?? seperti yg diketahui disc layer mestilah double layer utk membuang haba panas.dan soalan yg seterusnya ialah boleh ke pakai steering rack E36 dan drive shaft Z3? pernah terbaca chris punya solution from 4 lugs into 5 lugs.boleh ke di 'convert' kan? Z3 drive shaft and E30 are the same spec? can fit into diff?

Bro, this is not 'a question' nih, banyak nih. From my not so knowledgeable knowledge, here is my answer;

1. Cross-drilled a non-cross drilled disc? Can be done. Saw it before. But, u are jeopardizing ur own safety to do that. No short-cut for safety OK? The specs is not the same. My advice, get the ori cross drilled if u want.

2. Pakai E36 steering rack into E30. Can. No prob. U'll get more cornering ratio. Syiok! A lil' bit mod will be needed.

3. Z3 to E30. Macam pernah dengar. Need more facts bro. Maybe Chris can help =)

Hehehehe... thank you bro.was thinking to cross drilled front and rear disc so that the brake will be more gippen... now gonna get other optionla to buy that things.brembo disc ke?? Mati mcm ni... So chris how bout u?
can fit a Z3 into E30 ke??

Even factory cross drilled discs can eventually crack around the holes under hard usage. So sending your stock discs to be drilled by some random shop is not recommended. Go find some new Brembo slotted discs.

ya change all new parts.
better to have some peace of mind

hehehehe.... ok.will consider that
btw,thanks guys.
