> [@SRS!3](#): > > same brake conversion lines and all??? > now i need 5 lug conversion. You can use a common hole and make your rotors 8-hole, 5/4 lug, just redrill as for lines I used the stock flex lines that are factory Z32 lines, if you get lines with your calipers, otherwise the stock 240 lines will not work ---

The 300zx brake conversion has been covered more times than Jenna Jameson’s face. 1. Yes, sames lines. 2. No, drill your rotors to 4 lug. look here: > **[The Definitive 300ZX Brake Swap](http://importnut.net/300zxbrakeswap.htm)** > > Why do this swap? What are the benefits? The primary purpose is to improve the overall braking performance. This is accomplished by installing larger rotors and calipers.

you can use stock lines - the 240sx end fitting will thread into the z32 caliper ---

> [@spd-dmn](#): > > you can use stock lines - the 240sx end fitting will thread into the z32 caliper You can but it’s a bad idea. The Banjo fittings can come off. I think his question was do both the 26mm and 30mm calipers use the same lines. Yes. You can also use the stock 300zx lines as long as you have both parts. The Z uses both a short hard line (whick mates to the caliper) and a rubber line which mates that hard line to the chassis. The 300zx rubber line is a perfect fit to the 240 chassis. It’s just rare to find someone selling calipers with the complete (2 piece) Z lines. That, and most times people are looking to upgrade to stainless steel lines anyways. ---
