Can I swap 4 piston calipers for 6 piston?

I just traded some brake parts and had similar question. I went on their website and compared parts lists included in the instruction pdf for 2 kits. You can tell what wouLd be needed based on the part numbers being different.

Ultimately calling Wilwood tech is safest bet. I did that to confirm as well.

I'd think you need calipers and caliper brackets at minimum.

tmadden,

From a dimensional standpoint, you will find that most all Wilwood 6P/4P are lug/radially identical from model to model.

For example: If you currently have a SL4 you could purchase the same style (lug/radial mount) SL6 and it will be a direct replacement.

We have "black" SL6R (1.62/1.12 pistons) "radial mount" calipers in stock. They are for 1.25" wide rotor applications if this suits your specific needs.

Thanks Guys. I appreciate the advice

I was looking through your site and saw that the SL4 and SL6 kits were obviously different prices. I figured the parts were different causing this but since they are very similar, why is the SL6 kit cheaper than the SL4? Is this just a special running? Wanna make sure I am not going crazy..:lol:

Hi JsTA,

Good eye! Of course there is a little story behind it.

Basically GMR bought bulk of these a little while back, and at the time "WILWOOD" sold the SLR4P's for more than the SLR6P's (not my policy... but Wilwood's). Since that time Wilwood has changed it's pricing structure to the more common sense method of charging more for the 6P's.

GMR has basically just marked our calipers relative to what they were bought for at the time. Hope this makes sense. As you will notice GMR has these BNSL6R/BNSL4R's priced very agressive either way and is a great value as we are wanting to move them. Keep in mind that these are the "billet" SL's and not the "forged" ones that are coming in "most" the current Wilwood kits. The Billet ones retail for approx. $100 more per caliper than the forged. So you will see these calipers we have are priced seriously agressive.

If you are interested in front & rear I will see what I can do about another price reduction :thumbsup:

Thanks, Jay

Jay, thanks for the response! I was mostly looking at pricing just to see what kind of range they were in compared to other big brake options out there. I am in no place to buy these yet as much as I want to but am trying to figure out for when the time comes again to start up on the car. I really like your floater setup and would like to do something like that for my car in the future which is what ultimately lead me to your site.
