Any one tried Racing Brake rear upgrade?

[ryneen]

I'm curious if anyone has actually used the RB caliper mount and larger rotors. Can anyone comment on quality and performance? I know Science of Speed does not carry them any longer. Would love to know details as this seems like a great idea.

A couple of years ago I did the Racing Brake upgrade with the two-piece BBK 324x28mm rotors in the front and the NSX 1997+ type one piece 303x23mm rotors in the rear. This was on my '94 NSX.
When I bought my current NSX '98 NSX I already had the 1997+ brakes of course, so, at first, I only changed the front brakes with the same Racing Brake front kit.
About two months ago I installed the Racing Brake 330x23mm rotor rear brake kit. This is all with the OEM calipers.

So far, I like this kit a lot. The car bites down much better with these oversized rotors and, of course, the larger brakes also happen to just look good under my 17/18" wheels. It is very easy with these brakes to reach the limit of your tires (I'm using 235/40/17 front and 265/35/18 rear).

The only complaints I sometimes get is from passengers who sometimes get scared if I for example take an off ramp at full speed and brake down hard at the last moment. Just because I can... :smile:

i had the rb f&r kit on my 91 and was very pleased with them, track performance was much better than stock. only downside is rotor cost (replacement rings were about $200 each, complete rotors closer to $300) and they didn't get along with some pad compounds, carbotech in particular.

ryneen - I know you track your car quite a bit (i'm actually so jealous!). Your link points to the OEM NA2 size as a replacement for the NA1 size. Did you mean to go with their oversized 330mm kit? What front brakes are you using?

Good point. Thanks for the info on the 330mm. Damn that one is quite a bit more money though. Might as well get a Brembo BBK.

I had them on one of my first NSX's front & rear.
I liked them and they worked very well with OEM Calipers.

Have since gone to Brembo's.

advantage to rb is own caliper w e brake. brembo you have to pay $1k for the ebrake.

what is the reason you wish to try these? From what I remember Billy liked the way your car performed as is.

Yes, Billy did like my setup as is. However, I need to replace my rear rotors and thought that I'd upgrade at this time. I do believe there is a bit more stopping power available from a larger rear rotor. A larger caliper from a true BBK may be a bit overkill and make the rears bite too much. This RB setup uses the stock caliper so there isn't a substantial amount more bight... just a little bit more, which is all I need.

I have the Racing Brake 328/330 slotted kit. Went Autocrossing with it and it worked beautifully with my Project Mu pads.
Here's what they look like in 17/18, note the newer black carriers around the calipers (and my sagging wings west skirts :tongue.

Heading up to Streets of Willow this coming weekend and will let you know how they perform there...

What are your thoughts on a solid/monoblock (non-floating like OEM) caliper? I find that the pedal feel is significantly different and better even when the rotor sizes are the same (e.g. Spoon calipers).

This is why, even thought, clamping force might be close to the same, i'm completely sold on getting better calipers. Lighter and bigger rotors would just be a plus. It's just too bad they're quite expensive.

Thoughts?

On a side note: I've recently driven a friend's RS4. If I can get the NSXs brakes to feel like that it would make me want to drive the car even more. They were phenomenal. Even the C6 Z06 6/4 pot brakes in the Chevelle feel way better than the NA2 set I have on the NSX. It's not a feeling of an over-boosted set either. I think i'm sold but hoping to hear more opinions please

Any thoughts on using a stronger compound pad in the rear? Or an adjustable brake bias adjuster? Seems like a more cost effective route to do what you want

Hi,

i have 97+ sizes RB 2 piece on 4 corners with Project Mu levelMax 900i pads and i have a problem:

- high grinding noise comes from right wheels when cornering left and from left wheels when cornering right.

- going straight when the wheels travel up and down their wells due to road ondulations.

i brought it down to RB rotors or Project Mu pads, alone or incompatibility between them. As soon as i change to oem rotor and pad in that corner, the noise stops.

I really love how the car brakes, but for street use, the noise becomes weird.

Do anyone have some clue about this?

Thanks,
Nuno
