Hey all, two quick questions that I couldn’t find a clear answer on. Hoping you guys could help me get to answers please? 1. When using FI on the FA20 what is considered to be the real tipping point where you really start to risk bending a rod? Cosworth appear to say 280bhp at the flywheel is as high as they recommend you should go on a stock engine. But does anyone have any experience or has heard of rods bending below this level of power? 2. Which FA20 supercharger has the best whine? I know there is a lot more to supercharging your 86 than just how it sounds, but whine on a supercharger is a glorious thing. I’ve seen the MRT video for their Sprintex charger which is the best i’ve heard so far. Is this generally considered to be the one with the best whine? Cheers!

LOL cheers for the share. I enjoyed reading that Wikimotors need to stop hiring children to write their articles lol 400bhp on stock internals. That may last 1x dyno run before lunching itself. Let alone 500/600. I wonder if anyone on wikimotors has even ever seen a car before.

I’ve had a brand new condition set up for sale now for ages and I’ve still not managed to sell them even though I dropped the price down to just £150. I wish they were worth more but they just aren’t But best of luck selling yours

Yep still got them. Feel free to drop me a message

Hey All, Does anyone know if the facelift 2017 spoiler has any genuine differences in downforce/drag compared to the pre-facelift spoiler? I searched all over the net and forums but I cant find the answer to this. Just to be clear, I’m talking about this Blue Pre-Facelift spoiler Vs this Black Facelift spoiler below. I’d like to know if there was any genuine airflow improvements made by going to the facelift spoiler or whether they are both purely aesthetic. And does adding the Perrin Risers to the Facelift spoiler actually increase downforce? Or again are these mainly a visual thing? Cheers!

Bump. Dropped price to £160ono

Yes I still have them. Dropped you an IM

Please drop me an IM if you have an ECUTEK programming dongle kit for sale. I need to do a spot of data logging. Cheers! Leeky

Very nice I didn't realize STI did a Gurney flap. And they talk about genuine testing/results too! "After comprehensive wind tunnel testing by STI, this product has been developed to increase downforce by rectifying air flowing over the wing surface, without increasing air resistance (CD)." I only knew about the Perrin one which looked like it would remove its own screws after a while lol Verus did some great analysis into the perrin gurney flap on the BRZ - https://www.verus-engineering.com/single-post/2016/10/17/Subaru-BRZ-Perrin-Gurney-Flap-Analysis Cheers for the tip! I'll certainly look into one of these. A gurney flap is probably going to be ideal for me. As I have the Cosworth Exhaust that hangs low it fouls pretty much all the diffusers on the market.

Thanks chaps. A diffuser does sound like a good idea and there is also some stats on the Verus website about the lift reduction. I’ll certainly look into it!

Thanks for the advice but I’m an experienced circuit driver/tuner and my car is already set up to my specs. Just simply dialling out my few remaining gripes with the car and now looking for some rear downforce. What I really struggled with recently at Nurburgring and Spa was high speed cornering. The rear felt too light/numb when pushing power on through the longer/faster bends. I don't want to make any further tyre/suspension/weight distribution changes as i’m very happy with its grip/balance as it is. I currently want to improve rear feedback/feeling/confidence. What I do lack is any form of aftermarket aero; totally factory from the outside and I think with every else on the car dialled up its going to be hard to go any further with it now whilst still keep the outside looking stock.

Thanks MartinT. Yeah the 2017+ spoiler doesn’t appear to be worth buying for any functional benefits. I’m now looking for alternatives.

Ok cool, thanks chaps. So ideally what i’m looking for is anyone with first hand experience/knowledge of these Maxton spoilers. My car spends 99% of its life on track so fuel economy and looks aren’t important to me. Im really looking for any noticeable/measured improvements in downforce/aero without loading up the car with a load of expensive aftermarket parts that may not actually aid track use enough to warrant their price. This Maxton spoiler attachment may well be stick on tat but it does have quite an aggressive angle and assuming its actually rigid it should cause some kind of airflow change (whether its a good or bad change is to be debated).

Cheers guys. So from that BRZ document there is suggestion of genuine aerodynamic qualities in the 2017+ spoiler but these seem to be compared with a car without a spoiler rather than an improvement over the earlier spoiler - “The change to a "pedestal spoiler" design improves aerodynamic performance, stability and control over models without a spoiler, as a high-performance rear spoiler that provides more than just looks.” ”Faster airflow beneath the wing helps to generate downforce which in turn improves stability and control compared to models without a rear spoiler.“ So there doesn’t appear to be any figures that confirms the facelift spoiler is any better than the pre-facelift. Which is great as in that case I can see there being no benefit of upgrading. However, in that case has anyone got the Maxton Spoiler extension on their pre-facelift spoiler? I’d be keen to see if anyone has noticed any downforce improvement on track with one of these.

Any deals on Cosworth Superchargers?

I’m also running an Auto 86

Its a cool road. Good that you managed to get it on a quiet day. Usually is full of caravans and bankers on push bikes. I prefer the San Bernardino. Just as its always quiet and more pretty, but a bit short which is a shame.

Thanks for the offer but I’m not that desperate for the space.

Yes i’ve still got them. Drop me an IM in you want them.

Bump. Dropped the price to £170ono as I need the space. These are basically in brand new condition.

Sorry to drag up an old thread, but does anyone know what are the biggest rotors you can fit with the stock callipers under the stock 17’s? I’m totally happy with the performance of the OEM brake setup with decent pads, but i’ve seen a number of bracket/spacer kits online that allow you to run up to 322mm front discs with the stock caliper. If I can keep the stock setup and just get larger discs in the future which cost about the same but dissipate heat better then its a win-win situation for me.

Unfortunately not. They are at a mates place and these are the only pictures he sent me. I would ask him to take more, but it’s getting dark and we’re both off to the Nurburgring tonight. We wont be back until next weekend so could try and get some more pictures when I’m back.

Same on mine and every other 86/BRZ i’ve seen. I think they are all like that (prepared to be corrected on this). I think its just a bit of a weak build quality area.
