Your insurance will drop you like a hot patotoe when they discover you have modified the cars braking system. Regards Peter

Shame you live so far north. If you can make it down to Castle Combe at the end of this month you can watch me have another go at making the car flip. Coming over Avon Rise last year I was hitting 110-115mph and then having to hammer the brakes to take Quarry. Made it each time

I'll be having another go next month if you want to watch. I'd even be happy to take you out for a passenger lap if you feel brave enough LOL.

And the car is happy enough when braking on normal roads as well.

And as far as insurance goes, the last two insurers were happy enough not to suck their teeth and go "oooh, that'll cost you". They were quite happy with the explanation that I used original Volvo parts.

Oh, and ask yourself, what size brakes and which calipers did the later P2 T5's run? Good enough for plod as well ................

Haha... I was wondering who would show up first lol
got any tips for replacement disks and pads? Not for race but fast road if you know what I mean I have mintex pads and (I think) brembo disks and they're pretty bloody awesome.

Apologies but I just run genuine Volvo stuff, discs and pad-wise, not even plod pads. Works for me on and off-track.

But I'm a smog generator. The angelic types in the petrols reach higher terminal velocity so might disagree.

ebay bargain

Just got 2 calipers for £70 delivered

Martin, can you remember if you needed a specific type of bolt or what size ? Just to save me faffing about on the day.

[martinrpeachey]

It's M14 coarse thread but I can't remember how long it needs to be. Something like 50 or 60mm but I'd get a 70mm and cut it down. It needs to finish flush on the caliper.

[martinrpeachey]

What bothers me about that listing is the lack of info - there's several sizes of disk the XC90 uses and I'm not sure if it's the caliper or the stub axle that governs the disk size with those.

emailed him so will know soon...... worst case I send them back or flog them on

Is it a hex head or an allen bolt ?

I'd like to say they look right but the pictures are too dark and only from one angle.

If they are size dependant, you'll have 316, 320 or 336 iirc so you'll still be on bigger disks than standard. And those calipers are real "bite-y". I found out pretty quick that the initial bite is pretty lively and will have your passengers headbutting the windscreen a few times before you get used to it.
My mate had a S80 D5 and when I let him drive mine, we nose-dived and stopped 10 feet from the first junction we came to hahaha

Normal hex, grade 8.8 or above. I'm gonna go see if there's any about in the workshop in a little while, save you a couple of quid.
