Hello, can anybody help with the diameter of the discs for my 2008 Gen 4 3.2 LWB? Midas sell the ATE brake discs in two sizes, 290mm and 332mm. Would either of these fit my vehicle?

Unfortunately my manuals only refer to the thickness of the pads. Any chance of asking mitsu what the diameter is?

Take the wheel off and measure?

I called the dealership and they don't know either, even the spare part drawing doesn't show it. I was going to measure this weekend but things got busy and there was a lot of S15 rugby... maybe I will get a chance in the week.

Am I missing something, are the dimensions there because I couldn't see them?

No the dimensions aren't shown but you said the dealer said the disc doesn't show on their program.

The disc is clearly shown on their program.

They just have to punch in your VIN and then use the 51117 PNC to get the part number of your vehicle.

Once he has the part number he can check for stock.

Best practice still is to take a wheel off and measure to avoid any mistakes.

Sorry but I meant that the picture on their system does not show the dimensions, he was able to find the part for me :oops:

Tape measure proves that the diameter is 332mm, now I need to decide if I want new discs or if I want to skim the existing ones. I tend to prefer buying new so that I know what I have got, but I also don't want to pay the stealer prices... Midas say they have an ATE disc for R950 each... is there much to worry about if I want to change the discs and pads myself?
