IAG Built| HTA86| >500whp| Daily driven for 150,000 miles

Yes, I am also very happy with Motul Xcess. I have used it in my car ever since the rebuild. Last oil change I used Motul 300V. It is almost time for another change and it will be interesting to see if there is anything different in the analysis. I will probably go back to Xcess again as I am not sure the 300v’cost is justified for normal daily driving.

Yamaha and others are running em. Only reported issues have been fitting Girodic pads. None that I remember with the rotors

Two pieces all round? Then your talking Users Girodisc which are expensive. He commented on handling improvement in this thread when they were new. DBA offers front 2 piece for less money, but Girodiscs are very light not only because they are a two piece design. They must to be thinner too. I just replaced a set of DBAs that went over 100k. So, my front centers (whatever the correct name is) are on there second rotors. Still not issues. I believe there is a trade-off be made here - more $$$ and more performance and likely less life, or more standard part and less cost. I might have gone Girodisc, but at the time I purchased brake parts I thought I might need a transmission too and was just saving money. Turned out that was a second faulty ACT clutch :)

I do seem to remember 1, and only 1 thread where someone mentioned noise. - seemed like there was a real issue, not one normally encountered. Search Girodisc here?

ADDED: Yes I'd rather have Girodiscs :)
It was simon, in this thread:


Girodisc SS brake pads and 2 piece rotors initial impression

Its part of the reason I've been trying to gather up a broader consensus of opinions from several members regarding the girodisc rotors.

I would definitely do 2 piece Girodisc again :) They held up fine through the winters
Thanks guys. Much appreciated.

haha I have to justify the cost/power ratio of their 4.5L kit, such is life modifying an NA car :(

Re: IAG Built| HTA86| >500whp| Daily driven for 150,000 miles



My aging Corsa exhaust with 95k miles on it needed to be changed out. I decided to get a 3" Milltek exhaust and I am very pleased with it! It is about 70% quieter than the Corsa exhaust and has zero drone. I'm really impressed that the Milltek was able to profoundly quiet down the car without restricting any airflow (still hitting 38psi and zero knock). The Milltek does accentuate the deeper, bassier tones of the car and makes it sound smooth and Euro-like, in contrast to the brash full-bodied sound of the Corsa. The car does spool a tiny bit faster with the straight-through design of the Milltek, maybe just placebo :lol:

Awesome! Sounds great. Who did you order through? I initially had a hard time getting ahold of one, and then I finally stumbled upon a vendor that had it to me within about a week :rolleyes:

I am also very impressed by Milltek. Definitely seems to flow very nicely, we actually have had to work on boost control a bit on my car because of the killer B header and the Milltek. I wasn't sure what to expect, but I like the sound a lot. I personally think there's still a good amount of noise when you want to enjoy the full experience driving hard, but it's nice to also be able to creep past when it's preferable to keep a low profile.

It's been a long time since I've been taught such a profound real-world physics lesson. The way both the airflow and the sound waves interact when you change even one exhaust bit is really interesting. I considered driving into bridge pylons when I still had my SPT catback on with my header and downpipe combo.

I had the same experience going from the Q300 to Milltek. It was so much quieter I was in shock. Car also has a catted COBB DP and honestly at idle it’s like 10% louder than stock.

Might be my old age, but I like it. I do semi miss how loud the Q300/Catless Indivia DP sounded at WOT.

Yep same here. Don't remember which sub site I used but it was vivid racing, the same ppl. I had a huge ordeal with a well known parts company, followed by lots of crazy quotes both for cost and transit time.

Vivid got it to me really quickly and for several hundred less than the other guys. I will order from them whenever the opportunity exists in the future.

The only thing I disliked about the milltek was the shiny polished tips, but carbon buildup handled that for me quite quickly :lol:

Since I removed my girodisc front rotor my clicking noise went away ... they are sitting in a box in my garage. Bought a set of non slotted girodisc Disc to see if it would make a difference, same clicking noise. I wish I knew what the issue was, I really liked them other than the noise

thanks User. I hate the drone that I have. I even put in Dynamat to quiet it down.

According to their tech support they've revised their fastener design within the last 5 years. It's similar to what brembo & McLaren uses. They claim to NEVER have any clicking/noise issues like you're having. Shot in to the dark but maybe try giving them a call and see if they can help you out. They do sell fastener kits.

Re: IAG Built| HTA86| >500whp| Daily driven for 150,000 miles

Hey there, thanks I’ll take a look at it, i think I replaced the disk with a custom non slotted version that I ordered from girodisc to see if it would help and at the same time changed the fasteners, that was in 2017 or 2018 I believe so I should have gotten the latest fasteners. I’ll double check with them

I don’t know that I would say that they never had clicking noise :) seems unfrequent though, as far as I know I am the only one who has reported this issue ... on iwsti

Re: IAG Built| HTA86| >500whp| Daily driven for 150,000 miles

Got several new hospitals contracting us, some of which are far and in unsavory places for the STi and GT4, so I decided to pick up a 2019 wrx limited 6spd :)





This car will stay STOCK :lol:

That sounds familiar, haven't you said that before?

I've debated a wrx for a DD, I bet it's a really nice balance.

The newer wrx feels very tame. Should make a great daily!

So... how long until it's on flex fuel and full bolt on? Haha all joking aside they make great power on just flex fuel without any other bolt ons.
