First of all, thanks to everyone for waiting patiently while we dotted the I's and crossed the T's on this one. We went through some 3D scanning processes, test fitting of 3D prints, and finally of actual parts to ensure everything was correct. FType rotors are HEAVY. The sample rotors we weighed were 39lbs for the fronts, and 33lbs for the rears, on a fairly heavily use car that had seen some track time so possibly brand new are even a lb or so heavier.

We have teamed up with very well known brake manufacturers Girodisc, to produce an exclusive to VelocityAP option for replacing your rotors. 53lbs total weight reduction for a full vehicle set, $2300 cost, with a further reduction in price for your second replacement as you can replace just the swept portion of the rotor and save about 50% of the cost. Production items will be read to ship in approximately 3 weeks, and we are ready to take orders.

Initially we have just tackled the 'R' fitment, the 380mm front rotors and the 376mm rears, but these are common to the SVR as well as the V6S so it covers the vast majority of vehicles.

Interesting. Bookmarking for when I need replacements. I haven't shopped around yet. Initially, the price sounds high, but I don't know what going rates are for rotors on the F-types and the stock rotors, if nothing else, just look too bland...

 

Thanks, Stuart. Great work, as always. A bit off-topic for THIS forum, but have you/will you be looking at fit for the F-Pace, as well? Obviously more opportunity on a higher volume model. Cheers.

 

I am saving up for the fronts now. My "small" 326mm rears are 16lbs so sort of moot for me, but the fronts are way lighter at 11lbs per in weight loss. Thank you VAP.


Have had girodisc brakes before....no issues in years of use every day in all weather on my last car. These are top tier parts. No noise. No issues. Great looking. Long wearing. My only worry is that they'll sell out.

BTW, they look great too.

1) Are these floating? Do you expect problems on track/heavy use if not?
2) how the joints handle road salt in winter?
3) ocd = need 326mm rears to match
4) given your reputation I would expect more tech info like vein design, heat treatment etc. We can now just speculate that there is nothing fancy to report

 

If you have the 326 rear in 3-4 years when I’m due, I’m in.

 

Ordered! Looking forward to seeing these in the flesh. I will be patiently waiting by my lift 😀

 

I would also be interested in F-Pace SVR replacement rotors too!

 

Yes, they are floating. They do have some anti-rattle clips so some might call them 'semi-floating' but Girodisc's R&D shows it doesn't affect the float at all. Girodisc is extremely well established in the track community, these will stand up well to track use.

Salt is always going to cause corrosion over time, but I would expect that you would have worn out/timed out the parts long before that became an issue. Lots of people running Girodisc and you don't see a big problem there.

I'm assuming you have a Base vehicle, we do intend to do the base rear rotors as well, although there's some consideration as to whether it makes sense just to fit the larger rear caliper and upgrade to the 376mm.

There's a ton of existing information out there on Girodisc stuff, they have been around for 20 years and have a phenomenal reputation. Not all of the technical information about them would be something shareable because it is proprietary. That said:

• Hats are 6061 Anodized Aluminum
• Rotors are a proprietary composition heavily alloyed grey cast iron
• They are subjected to a proprietary heat treatment process
• Front rotors have 72 vanes, rears have 48 - these are a conventional vane to draw from the center

 

Stuart, these are great! Still anxiously waiting for the Apex wheels for f-type!!

 

I thought the wheels thing fell through.

 

Still working on something

I have been saying this for ages, seeing as I did exactly that several years ago, it was not difficult and if I can do it anyone with some basic tools can as well.
A quick browse of Fleabay Motors shows dozens of used F-Type 376 mm calipers (with brackets) for sale, although the condition of some could be a bit dodgy and there are very few advertised as a pair, and no new ones that I could see. If buying used I would recommend getting a caliper refurb kit as well (mainly new piston seals etc).
Once you have the discs/rotors and the calipers (with brackets) the only other thing you need is the larger splash shields, cheap enough from BritCar.

 

I can say the following about the quality of Girodisc. A friend of mine drives a modified C6 Z06 and is 5x a year on the race track. Power of the Z06 around 750 hp. He also has these brake discs on his Corvette, and is completely thrilled. Whether he also always drives these on the racetrack I do not know, but on the road 100%. The parts must be mega, but can not say exactly which brake blocks he uses, but can gladly ask. This guy has a clue and is a gifted screwdriver. Based on his statement I would order these parts without hesitation, unfortunately mine are only 8 months on it :-( However, when I change I will make the exchange.

 

👀 have been looking for a nice lightweight forged option that's not $2000 per wheel and independently tested, very interested.

 

Very solid, when I'm looking to replace I would love to go for 2 pieces from a reputable vendor. 53 lbs is huge.

 

Thanks all for your patience. There was an atypical delay with the Zinc plating process but all outstanding orders have shipped and we now have a few sets in stock.

 

No V6S, I think performance brakes or whatever Jaguar is calling that option. Large fronts and smaller rears (cars without electronic vectoring by brakes)

 

If you have a V6S it has the same brakes as the Iron Rotor 'R' and our Girodisc product will fit.

 

Nup.
The V6S (and later the V6 R-Dynamic) came stock with the "High Performance" brakes, 380 mm front and 326 mm rear, ie the big brakes on the front but the small brakes on the rear.
The R came stock with the "Super Performance" brakes, 380 mm front and 376 mm rear.
The base V6 came with the "Performance" brakes, 355 mm front and 326 mm rear.
Both the V6S and base could be optioned with the Super Performance brakes.
My V6S came with the stock brakes ie 326 mm rear but a few years ago I updated those rear brakes to the 376 mm version.
So if you have a V6S or V6 R-Dynamic the VAP rotors will "work" for the front brakes only but not for the rear brakes unless the car was optioned with the Super Performance brakes or the optional 376 mm rear brakes were fitted later, and AFAIK I am the only one here who has done that.
You can't just whack the 326 mm calipers and pads on 376 mm rotors, they look pretty much identical to the 376 mm versions but they are slightly different and they won't fit.
Seeing as the V6S and base both came stock with the 326 mm rear brakes there is a bigger market for the smaller two piece rotors than you may have thought.
