Aftermarket Pedal assemblies

[Cmac]

For idea purposes and future plans how did you mount and set up your after market pedal assemblies.

Thank you in advance. I have seen some really good ideas on project builds but never in one place.

Here is my first ever mounting job of a reverse Tilton pedal box. It works fine, until I needed to service the pivot bolt (squeaking). I can't - a small oversight. In essence, I'll need to remove the dash to get to the pedal box - whoops. Didn't think of that scenario.

I'll post a better example next, but here are fab photos of the Bronze.

Here's what I learned, and did on Robs car a couple years ago. This Tilton set up clears the early gauge cluster, dropped the column, and mounted the pedal box in a way that it could be dropped out the bottom which was not possible on the Bronze's set up.


BTW –the rather large plates welded against the fire wall were necessary to cover up huge “modifications” by the PO’s. The drawbacks of building from a race car – I think James ended up welding 137 holes in this car at last count before painting the engine bay alone! Your plates do not need to be ¼ this size. The cage will take much of the strain, and will give most of the strength.



A couple of ideas for ya - since you asked

What's the reccomended master cylinder sizes? ... I bought one 7/8ths Tilton 75 series for mock up.. but then heard I should run three 5/8ths masters .. ideas?

Front: stock 280zx brakes ... Rear: stock 510 drums ... . Trans: either 280zx or KA24 ..... I'm using a 6.2:1 ratio Tilton reverse mount pedal box w/ remote balance

Indy,

I used the lower ratio pedal box as I was concerned with space restrictions. As I learned, my concerns were unfounded and there is plenty of space. I also made the mistake of utilizing the short M/C's, which are literally twice the cost. My experience now tells me that both parts, and their premium costs, are not necessary in use in this position in a 510.
Rob's car utilized the standard length, higher ratio pedal box with the standard length M/C's. He hasn't driven his setup yet, but the fit is good.

With my short ratio pedal box, I switched down to 3/4" M/C's, and they are not small enough. I need both legs and an arm on that pedal to haul the car down from any speed. I utilize 280ZX/drum brakes on the Bronze with Polymatrix A compound pads up front. My suggestion is get the higher ratio box up front, you'll be happier with the end result, especially on the street.

Referencing the current Tilton web site, and taking a complete guess at the moment, I would say I utilized the 75 series M/C's and the 5.5:1 600 series aluminum pedal box. I see that there are still listed 5/8" M/C's, it's be a good step in my car to recapturing some pedal feel, which is near zero at the moment due to the low ration. One positive aspect is that the pedal was/is plenty stiff – even when I had – for a brief time – all stock PL510 brakes on this car!

I'm assuming Cmac that this is the discussion which was desired at the beginning of this thread?

BTW Nice photo James The caption should read; "WTF!" The fingers did the walking, the expression does the talking.

Byron and Indy this in fact what I am after. When I started to build my car I thought about doing this while still trying to maintain the stock dash and no cage option. I still intend to do this at some point and after pointing the thermal temp reader on my master it is apparent something has to be done. The other cars I have seen this done to is Brads, Track junky and the wizard to name a few all great builds.

Feed back is great and I wish I had asked this question years ago.

[Byron510]

Cmac, I have looked at this from a street car point of view, and I can see no reason why this mod could not simply be contained and constricted to under the dash only. If you had the desire to cage the car, certainly incorporating the brackets required for the pedal box makes sense, but the full cage is not a requirement. The "dash bar" can simply be welded to the body just below the A pillars, it’s a very structural area and will certainly support the load. Thinking about it further, contain the necessary bracketry to the drivers side of the dash should be possible as well.

My further thoughts on the subject.

pictures of Gary K's 510 pedal box. I'm not sure if his setup uses the high ratio arms or the low ratio arms, but reasoning based on the era of the installation would suggest that it predates availability of the low ratio arms setup.

Here are a few links to more pictures of the beautiful roll cage work Byron did on my car.

Angle iron engineering! WOW that looks flimsy in that picture. It's still holding up after 40k miles. I would also recomment the longer pedals (higher ratio) as the pedal pressure is too high on both my brakes and clutch.

[510rob]

what are the peak pressures you are seeing?
