I'm just curious as why would you bother going with a 5 lug conversion.
What are the advantages of it?

Also, how much would the parts set you back?

Thanks.

 

Bigger calipers?

 

Is that really it?

 

no

even if it did, the caliper size has nothing to do with brake performance.

you get larger rotors, ventilated rear rotors, and 4 piston calipers up front. not to mention better wheel options.

4 lug has single piston calipers all around and solid rear rotors. it sucks, i should know.


how much does it cost? that depends how good you are at bargaining and parts sourcing...

 

Well, the advantage are bigger brakes, is more ventilated, and when you are going to buy wheels you have more chances of finding sizes 8.5, 9.0, 9.5 inches wide wheels than 4 lug wheels of those sizes. Actually, the other day my Dad and I were doin the conversion of the '90 5 lug to his '87 4 lug Rx7, which the S5 5 lug is bigger than the S4 4 lug. Also my Dad did that conversion a couple of times before and he swap his first gen RX-7 race car 4 lug and installed the second gen S5 5 lug which it fits perfectly

 

i can sell u the parts off of my 1990 gtu pm and we can talk about it
