I'm looking for lightweight rotors for my LS400 front brakes. I came across DBA rotors but cant find them for the LS400.

 

Im sure DBA can make a set....but I havent had any luck finding them for LS400 in the US. Brakes direct is an Australian company that offers them.

Look at R1 Concepts.....that is what I went with instead.

Or use TT supra brakes as DBA is offered for Front and Rear

 

Are the R1 concept rotors lighter than normal rotors which are around 20lbs each for a front?

I thought the supra tt front rotors wont fit the LS400 caliper as they are a bit larger in diameter. Is this not true?

 

The R1 concepts are probably around the standard 20 lbs.

The supra tt are larger than the LS400 rotors and slightly offset, so they wouldn't work with LS400 calipers. I'm sure he meant you could get supra tt calipers all around if you wanted to run DBA.

If you're set on getting the lightest rotors possible and you have the money, then you can always go 2 piece rotors. There is a company that wanted to produce them, but I can't remember if they followed through with it. The LS400 is rotor and E36 m3 have the same rotor diameter and thickness. You could get the replacement ring for the E36 M3 and have custom rotor hats machined.

Okay, that's what I thought.

I've looked at those 2 piece rotors but they are pricey.

I am actually trying to get my 93 supra under 3000lbs and swapped front the LS400 brakes from my SC300 with the TT brakes from the supra. The LS400 calipers are aluminum and were 10lbs lighter for both, the rotors were just as heavy as the supra tt but still shaved 10lbs of un-sprung weight off the front of the supra.

 

The initial cost is about $760, but the replacement rings should be cheaper than traditional rotors.

 

Stop Tech slotted rotors have a good reputation but come in around 23lbs for the fronts.... Not that expensive.....

 

Okay, I gotcha. I'm not familiar with the two piece rotors and didn't know that.

 

I assume each rotor is 23lbs and not for both of them, correct? I will look into those.

 

Since you were making the weight a priority, I tried looking up the weight of these rotors and I found ranges from 13-23 depending on the style and model car......

I just referred to the largest number I found....

Good luck in your search and let us know what you decide....

 

My Centric LS400 rotors are 20.75 lbs on average, but they were more like 20.75 and 22.75 lbs, respectively, with different thickness faces. I don't know if that's quality control or just how they normally do batches.
