Lexus GS300 rear discs

[TheD]

Apologies for putting this here but I couldn't find an appropriate forum.

Anyhoos....I was checking the discs on the car and the rear discs are only around 5mm thick. I decided of course I needed to change them and the pads. I checked auto data, and few online sites, and they all say it should be a 310mm vented disc. The ones that are on are solid. Can I do a straight swap out for the vented discs?

Thanks

Doubt you'd fit the caliper over them unless the pads were worn out!

Changing from solid to vented discs would involve changing the calipers and getting the right mounting offset. Maybe there are alternative vented and non-vented options and you could change from one to the other, but if so it would involve changing everything and not just the discs. I wouldn't assume that just because the same type of car has different brake options that you can freely switch between them.

You are correct.

It requires a whole change of all components. It seems although Lexus brought out the Mk3 in 2005 they never made the change to vented rears until some time in 2006. Probably using up stocks from the Mk2.

Thanks guys. I've ordered solid Ferodos and pads after talking to a stockist.

Just make sure what you're fitting does sit sensible within the caliper body.

Wouldnt be the first car I've seen were some moron in the past has fitted solid discs to a car that should be using vented discs which is utterly dangerous !

Something isn't right with them. I think it is a bodge. When they ran the Vin it says vented 310mm which concurred with my findings. I'll find out at the weekend when I take the wheels off. Plus they are rusty and don't look like they are making much contact (if any). I think you are spot on Stevieturbo

It will be plainly obvious whether the caliper is correct for the disc in use ( or at least it should be lol )
