Is there are part number somewhere on the packaging or the part?

I pefer the blue dial but the yellow is rare and eye catching. I'm a blue dial fanboy though; I've got a Tag Heuer Calibre Link 16 with a blue dial. Cant get it in the UK - it was a US special edition.

No it just toyota UK. They probably had a normal person try a 0-100kph and recorded the time. Edmunds in the US managed a 0-60mph of 6.5sec for the manual car..... obviously 0-62mph will be slightly more but you need 3rd gear for both.

GT86 power to weight 160hp/ton (1230kg) BMW 325i power to weight 146hp/ton (1460kg) Problem with the GT86 is that it can only do about 59MPH in 2nd gear. Area under the curve makes a difference too. I suspect the BMW has more torque at low revs compared to the flat torque curve of the gt86. not that I care.......

It appears to be the 350 collector?

Yeah its classic LSD clunk. I kinda like it. Makes the car seem a bit more mechanical and because RACECAR...

Absolutely! That thing is going to be a beast! Like I said you can fiddle the bais to your liking with different pads anyway I want a brake kit mainly to reduce comsumable costs. £150 worth of pads in two tracks days on the OE brakes

Sorry yes rears. The old brembos, I think have smaller diameter pistons than the STI rears that smudge is fitting.

I should point out where these bigger brakes can improve stopping distances. Not really applicable to stock GT86s but some with track tyres and more power perhaps. I'll give the example of a porsche GT3 that Colin Hoad likes to use as an example. Over about 150MPH the stock brakes of a porsche GT3 (dont ask me which model) cannot lock the wheels up no matter how hard you hit them. They will of course lock up once they slow down enough. This is actually intended by the engineers at porsche. ABS has a finite reaction time and slamming the brakes at 180MPH can make your starfish twitch. In this case a bigger disc will allow you to lock the wheels up and potentially increase stopping distances from very high speeds. I dont know what the limits of the stock brakes are on the GT86, but I'd expect a 300hp GT86 with grippy tyres to hit 150Mhp down bentley straight at snetterton.

Are the gold brembos the same as the 08+ STI calipers?

The STI rear caliper piston has 2mm smaller diamater (36mm vs 38mm stock caliper) which when combined with the slightly larger diameterdisc, brake torque is more or less the same within a few %, but yes it moves it forware ever so slightly. I cannot stress more that bigger brakes over OE (which is more than capable of locking the wheels) will absolutely NOT reduce stopping distances. They serve to give better heat capacity, nicer pedal feel and aesthetics. Back to back test are so massively subjective. We are talking about fractions of seconds here. I've tried a car with the sti brembos just on the front, and because of the larger piston diameter you do get more pedal travel, which for me was offputting. Im not knocking these setups chaps (I have an ebay saved searches for the STI calipers , I just want to make sure everyone knows the facts and can make an informed decision. At the end of the day, you can move the bais back with different pad compunds. This is a very common way to do this and works well as long as you stay within the operating temperature of the pads.

Church makes some important points. The Subaru impressa is front heavy and has alot more weight over the fron than back. Smudges setup does move brake bais forward about 16% (i've run the nubmers myself to confirm) which is undesirable but workable. With firmer springs on the front, you'll actually have less weight transfer to the front so really you want to move it back a bit over stock. That being said it wont stop any slower or faster (when cold) as both are capable of locking up the wheels. You will gain a whole lot of pedal feel though! and massive heat capacity, especally if you are going for mega power with a big twin screw SC Also note our cars dont just have abs, we also have electonic brake force distribution which help sort out the slight shift forward with this setup. There are cars in the states running down force (element tuning hydra) whereby the EBFD cant keep up and they had to develop a new brake setup using the wilwood calipers to move the bais back quite a bit. There really is no perfect setup for our cars. Different track conditions, tyres, suspension, diff settings, corners all have slightly different ideal settings. F1 drivers actively change brake bais, diff setings ect as they lap a track. To kep close to stock brake bais, perhaps the brembo or Ap racing setup is optimal, but at £4.5K+ this is a much more cost effective way to get more heat capacity for track. You can put a more aggressive compound on the back to move the bais rearward a bit.

I think the AMG golf is FWD though isnt it? Personally i'm not a fan of runnnig lots a roll bar. The firmer the bar, the less independant the suspension becomes. The clubsports are a decent damper, so 8kg front and 9-10kh rear should give a tolerable ride when properly dialled in What pads are you using with a APs?

Great videos. The philosophy of soft spring and firm roll bars is definitely an old school British thing, and aimed a lot at rally driving. 6kg rate are okay. Bit of a compromise for road use, but the roll bars will help. On your tyres, to optimize lap time, id look at 10kg front and 12kg rear. It all depends on how much of the compromise you willing to make. Are yours the 3 way or 2 way adjustable clubsports? What's the longest session you had? and how did the AP brakes hold up?

For a start you'll be applying 20% VAT and 3%? automotive import duty. £5k to ship it across? Thats about £30k so far. I think its a nice package IF it an be had for £30k. Bilstein dampers, bigger exhaust, bigger brakes.... Add all that lot to a stanadard gt86 and you'll be getting on for £30k.

It wouldnt need to be much design work, just tweak the piston bores. I cant see them do it to be honest, not for a limited run. Our cars do have electronic brake force distribution which helps iron out brake bias for whatever reason (hitting a banana on track?).

They are nice seats. I wonder which Bilstein damper they are using. B6 is my guess. The STIs are nice looking, but I bet they are using a more aggressive brake pad compound at the back. Either that or they have made the front caliper pistons smaller (or the rear caliper pistons bigger) but likely they are just using off the shelf STI parts.

Whilst something like this can help, it wont eliminate oil surge if you are generating too much G force too often, it isn't a guarantee. In extreme situations such as running slicks and downforce, the oil simply doesn't return to the sump in order to be picked up because the forces are holding the oil in other parts of the engine. Certainly running road legal tyres something like this can help. I will have one fitted as a safe guard as I do tracks day fairly often. I'd always recommend having an oil pressure gauge when doing track days. For two reasons: 1) to observe oil pressure drop as oil gets hotter. 2) to watch for oil starvation on long high-speed corners. (you get pressure drop when oil isn't being picked up)

I wonder if that is 350matt that seems to be involved in anything Cosworth on the forums? He's gone quiet recently though which is a shame.

Any on this side interested in the group buy? Group Buy: 1) RastaMau5 2) Kodename47 3) Smudge?? 4) Deacon 5) 6) 7) 8) 9) 10)

They are probably be just as good as the AP for general track days (short non competitive sessions) and road. Probably not as good if they are on the ragged edge being used with Race pads up to 1200C though...... but who knows. They could be plain ap discs that Reyland machine themselves. They seem to offer the J hook (thought that was an AP Patent?) on their discs too.

Have you ever tried Reyland discs? I wonder how they compare to the AP equivalent? Generally they are £200 or so cheaper for a 330mm disc! If you believe the AP blurb, the sinusoidal cooling fins have a significant effect on cooling performance though....

You cant go wrong with Reyland mate Do they have all the measurements or have you sent them a hub? I'll be interested how you get on with the Wilwoods as I have very little experience with them.

It looks like the MOROSO one....

Dave its going to be amazing when its all done! May I ask, who is making your bells and brackets for the Discs and Calipers?
