CSR Elite Pedal Tweaks

[eKretz]

I posted this in the wheel mod thread but figured people with just the pedals might not see it there so I'm giving this its own thread.

I have really not been perfectly happy with the CSR Elite pedals as far as feel since I got them, so I decided to do a little tweakage. I added 2 R/C oil dampers from one of my old trucks and made custom pistons so I get damping on compression and hardly any on rebound. Used 3000 wt. silicone oil. I also switched the load cell mounting point to the hole that gives more leverage; however, this made the pedal way easier to push, which I didn't like, so I disassembled the pedal completely and pulled the rod out of the top of the load cell's plastic block. For those who didn't know this, the rod going into the block is not 1 piece, there are 2 separate rods and between them is a piece of material that acts as a stiff progressive spring. To help stiffen things up and make the pedal feel better, I added a spacer in between the rod and the spring material. This increases the spring rate and makes the pedal stiffer but gives a good bit better modulation at the end of travel because the leverage ratio has been increased...a very big improvement IMO. Loving it so far, feels much much better and also gives quite a bit better modulation at near lockup.

BTW, the little black and hot pink nubs visible in the photo are just pieces of silicone R/C nitro fuel tubing threaded onto the bolt ends to prevent my son from mangling himself on the semi-sharp jutting metal. He just loves to climb all over those pedals and—this part drives me nuts—turn down my load cell potentiometer. So basically every time I fire up for a race, at the first turn I'm into the wall!

Haha, Sounds like my toddler with my guitar pedalboard. I had a hard time following exactly what rod you were talking about here, any chance of a pic of where you placed the the spacer? I like what you did with the RC shocks, very creative! Ever thought of doing any kind of slave cylinder fluid resevior type mod? I too love my Elite pedals

OK, I've circled the rod in question in yellow in the original bottom photo. This is attached to the pedal with the shoulder bolt visible in the photo but is just slid into the plastic block and can be pulled right out. The spacer is installed under this rod inside the plastic block. I used a piece of steel about the same diameter as the rod and tried different thicknesses until I liked the feel and modulation.

Yeah I entertained the idea actually not a week or so ago, but then I tried this and it works so good I'm not sure if I will still try it. It really feels a lot better and gives better braking control. I went from best laps of 1:45-1:44 at Laguna Seca in iRacing with the MX-5 Cup to 1:42.9! Now I'm averaging in the mid 1:43's, and that's right off the bat.

Sick Kretz!!!! The times are a definite benefactor when you can get the brake to act as a brake should with some damper/hydraulic tension. I have the Dave Struve Brake-Mod kit on my V1's, and couldn't be happier. If you could produce & market that e, you likely would get a minimum +-100 orders on first go.

At Watkins Glen in Cup car, I am running 1:09.500's, F1-50.937. Before the mod, add a minimum 1 second to each lap. Now, is some of that me, of course, but the brake-mod added confidence I never knew I had going into turns.
