Neon SRT4 front brakes on a 91 Spirit RT

[Wastelands Warrior]

Just wondering if this is a feasible swap, as Wilwood makes a nice bolt on big brake set up for the SRT4. I have BC coilovers on the front, so is it just a question of picking up the SRT4 knuckles and ball joints? Or am I missing something

[cordes]

From all the reading I've done, the turning radius will be poor with the knuckles from an SRT4. There were a couple years in which the PT cruisers supposedly had a proper turning radius for our cars, but the knuckles are only from a PT with manual trans. I think I may have a set, but I don't know how to tell for sure. I've thought about doing just what you're talking about.

That said, R/T brakes with appropriate pads have not faded on me during track sessions. Have you tried that yet?

I am wanting to do the same thing. In for information on which knuckles I need to source.

TCE has a kit that bolts to the stock R/T adapters using willwood calipers.

I thought that was a 1-off kit? Plus, I want to run Viper calipers, since I already have them, which the SRT-4 has had adapters made for.

There's an adapter for Viper brakes on SRT/PT knuckles? Paging Jon Trotter, paging Jon Trotter. I've been toying with the notion of making a bracket to adapt them to our knuckles, but that seems like more trouble than it's worth for me. I would like to do a CF hood for my cars, and that'll drop a lot of weight out of the car. Do a CF hatch, and there goes a ton more. That's certainly enough to affect braking needs and balance for sure.

I should say I know it's been done, so the design already exists by a company that *should* be able to make more for the right monetary encouragement.

Decided to pick up a pair of SRT4 spindles and give this a go. According to Wilwood their set up will work with a 15 inch wheel which will allow me to run my 16 inch Pumpers

Haha I just saw this. Would love a brake upgrade, last time I ran 125 at the end of the track and ran out of pedal over a 10 minute session. I'd love more options too for pads since I'm running the Daytona brakes that Hawk DOESN'T make pads for. Something to adapt a larger caliper would be nice, but if I have to go to larger rotors, so be it.

They won't re-puck backing plates? I know Carbotech and Porterfield both do.

Porterfield will make pads for any plate you want, in any compound you want. Also, make sure your're using really good fluid and change it often.

Here are some of the dimensions I found when we discussed this before.

Thanks for this! I'd forgotten about it!

Seems to me the turning radius shouldn't be affected by much, and if you have super wide tires, might prevent rubbing on the transmission case or wheel wells.

So I have been trying to look this up, but haven't found much of anything...how "stand alone" is the ABS system all together in the SRT-4? For those cars that didn't come with ABS at all, this might be a viable solution and could REALLY help out the performance potential of our cars.

[Reaper1]

So I FINALLY found the wiring diagram for the Neon ABS. I don't see any reason why it couldn't be installed as a stand-alone system. 2 power feeds, a switched power, brake switch, "traction control" (which I can't figure out what it would do since it doesn't interact with the ECM), 2 grounds, and a data-out (which goes to the data link connector...DRB2?), and of course the wheel speed sensors.

Seems to me like it's fairly straightforward.

So I should try to save the ABS off my PT GT?
The traction control on these used the brakes to control wheel slip. Low speed traction control.

Neil Emiro put this system in Chris' GLHS that was on display at the Shelby Museum. I believe it was essentially a standalone.

[Reaper1]

Well, that kinda answers that, doesn't it! I wish I'd have latched onto that idea a long time ago. Ugghh...

[karlak]

Will the master cylinder handle the bigger brakes. Is there a upgrade master cylinder we can use?

It should, and if not, yes, the older Dodge D150 master cylinder can be made to work if more volume is needed, but it will require higher pedal pressure.
