CJ Lancer vs Ralliart brakes

[BKTJMS]

Hey all
We are building a CJ Lancer into a race car and a key component to the race car is brakes.
What we are trying to figure out is what is the differences between the standard cj lancer and the ralliart in brake components, what is interchangeable etc.
Any information will be greatly appreciated.
PS. before anyone says, yes we know that it would of just been easier to buy a ralliart but the car has to be naturally aspirated for the series it is entering.

Thank you

Sounds like it needs to be a budget set up as well?

kind of yes, which is why we are looking at ralliart brakes and not evo

the dba bible is always my first go to https://dba.com.au/wp-content/uploads/2022/07/F721-CATALOGUE-2020.pdf

base spec is 276mm by the looks, and CJ ralliart is 294mm. just need to compare pad part numbers. If theyre the same, its the same caliper with a different mounting bracket (longer legs) to achieve the different spacing for the larger diameter.

thanks that helps us a lot.
The pads are different so will need to change calipers too.
tbh just answered my own questions lol but different websites were feeding different info and it was getting confusing.

A bit late to the party, but just wanted to point out that Ralliart front brakes are twin piston while the base CJs are single. The fronts will bolt up, the rears have different bolt spacing for the caliper.

Most 2.4l CJ Lancers had 294mm front and 305mm rear discs and the 2l low spec versions had 276mm fronts.
The 294mm fronts are same diameter as Ralliart but the Ralliart discs are 2mm thinner and prone to warping. The Ralliarts are indeed twin piston calipers and the Lancers single caliper.
I ran a CJ 4B12 with 220HP on the stock 294mmm single pot front brakes with "Brembo" ceramic pads. I had no complaints about the stopping power but there are some issues with ASC/ABS being a bit heavy handed - most likely calibrated for the smaller rotors in the 2l variants.
What makes a massive difference is a Quaife QD25E LSD that has an amazing effect on not just traction, but helps to distribute braking force from side to side as well! That fixes the ASC/ABS issues nicely.

I actually just bought some CJ Ralliart calipers for my ASX to upgrade.

I’ll update my thread when I get them installed.
