I was curious if there was a site to look up vehicle manufacturer specification on a vehicle by its VIN?

For example, I'm interested in buy some new rotors and calipers but I want to find the exact measurements before doing so (i.e. - what are the sizes of bolts in the front rotors, rear, etc.). And not that I don't trust information from third party websites to have this information but I want to make sure everything fits when I take everything out.

For my specific case, I have my 2007 Subaru Impreza 2.5i but I can't find any information on the braking system in the owner's manual.

Also, I tried searching on sites like the ones below but they don't contain the specific information that I want.

Let me know, thanks.

  • The vin detail most probably will not give detail of bolts and sizes but normally does specify equipment fitted : radio type, tyres, trim level etc

  • You need the service manual, not the owner's manual. Or, easier: call the dealer and ask them. They probably won't have bolt sizes, etc., but they'll have part numbers. If you're just doing brakes, you shouldn't really need any new bolts - just the new rotors and pads.

  • Local dealership can look up the parts and give some specifications, especially fasteners.

  • @rj2700, Are you looking to use parts listed as for, or from, a different vehicle? In most cases if the part is listed as compatible, it will be. Granted there are situations where a part is simply not available... But this is unlikely to occur with Rotors for your Impreza.

    @rj2700 As long as it's a reputable aftermarket brand, I am sure it will fit. Akebono, Tokico, StopTech, PowerStop, Bendix, Wearever, Duralast, Wagner etc. If it's a power-brand like "Brembo" and it's cheap, it's a bad idea full-stop. Other than that, if the manufacturer is claiming compatibility it should allow for return without issue if there are any problems with fitment.

A VIN number is a sequence of 17 number and letters that when decoded provide quite a bit of information about a vehicle. When read from left to right.

WMI( World Manufacturer Identifier) is contained in the first 3 digits.

Position 1: What continent your vehicle was made on.

Position 2: What country

Position 3: What type of vehicle,

VDS(Vehicle descriptor Section):

Positions 4 through 7: model info, body type, engine type which is vehicle specific.

Position 9: Is a check digit for verication of VIN #- no vehicle info

VIS(Vehicle identifier section)

Position 10: vehicle year info

Position 11 through 17: Plant #, extra options , manufacture sequential number etc which varies from manufacturer to manufacturer.

For vehicle specific information check their websites or talk to the parts department guy at a dealer- the information would probably be on his computer.



Go to opposedforces.com type in what car you have and it will tell a through z bolt nuts spacers washers everything basically a turbo and non turbo model is shown and diagram is pretty easy to understand it helped me hope it helps whoever reads this
