Thank you, I gotta admit I’m pretty pleased with how they have turned out - a lot of sanding, filling, rinse and repeat
. I haven’t fitted them to the car since they have been finished but they should be okay…..Did the final touches today:
1/ I fitted thin neoprene strip around all edges to discourage rattles and help seal the enclosure against the door.
2/ I soldered on XT60 connectors. These are more commonly used to connect lithium iron batteries to RC cars but are very good quality and can only be plugged in one way.
3/ I wrapped the wiring in cloth tape to ensure no rattles.

This morning I soldered the new connectors to the cars wiring loom and fitted the tweeter pods - all this went smoothly with no issues. Fortunately my good friend, and fellow audio nerd, Dave was also available and so we (he really) set about tuning the DSP to the new wide band drivers. The Helix drivers are significantly less sensitive (85 dB) than the previous Hertz tweeters (91 dB) so that had to be addressed and also the mid/bass drivers had to be rolled off a lot earlier at 500 Hz. The result is surprisingly linear and the FR is surprisingly flat right up to 20K Hz. As for the sound - well that is quite transformed. The soundstage and instrumental focus is now very tightly focussed with everything happening at the edge of the bonnet and windscreen. The soundstage is also higher up and level with my head. the mid range is more expressive and clearer and even the bass is improved with greater attack, punch and clarity.
Hi Mark.
Very impressive work with the tweeter pods!
Quick change of topic.
What tyres/size do you have on your car?
I am sure you said you had Bridgestone.
I have read and re-read most of the tyre related threads on here and I cannot decide between Michelin PS4, 4s, 5, 5s and Conti CS7. To make matters worse I really want the Bridgestones that won the Evo mag 2025 test.
To simplify my life I will probably just go with whatever you have.
You obviously do lots of research before choosing something so important!

Hey bud - thanks for your support

My tyres are Goodyear Eagle F1 Asymmetric 6 in 225/40 18. I have had two sets of front tyres and one set on the back.
I have no complaints at all regarding the Goodyear’s but I’m tempted to try the Michelin Pilot Sport 5 - just for the hell of it really. To be honest, you can’t go wrong with any of these top performing tyres. Just make sure you get one that also performs well in the wet as that’s real life rather than the dry track performance many tests focus on.
I don’t think the Michelin Pilot Sport S 5 is available in 18”.

SC7 are fantastic if you’re a hardish kind of driver I had them in 225 and they were absolutely fantastic,but seeing you live in a country that rains 80% of the time then ps5 maybe the best alternative.
The Conti CS7 does appeal to me too, but it’s one of those that’s great in the dry but nothing like as good in the wet - and the reality is that, as Model 500 says, in the U.K. it’s wet a lot of the time 
. Overall I think the Goodyear Eagle F1 Asymmetric 6 is the best overall balance and I’ll probably just get another set of those.

Can you back that up? I’m just curious, but in "typical" German tyre tests, Conti has been the clear winner for quite some time now, even in wet conditions.The Conti CS7 does appeal to me too, but it’s one of those that’s great in the dry but nothing like as good in the wet - and the reality is that, as Model 500 says, in the U.K. it’s wet a lot of the time
What I found in direct comparison to both tyres in favor of the Michelins they are better in really heavy rain and standing water,I still prefer the sc7s in all conditions apart from very heavy downpours where the Michelins really shine.

I have just had a quick look at both of these tyre tests.
They are both done by the same guy (John Barker from Evo mag) but they are separate tests on different cars.
The Evo test is particularly trustworthy because they do a lot of different tests and rate they tyres objectively (measured performance) and subjectively (how they feel) including a road driving assessment.
Across both tests combined the Bridgestone scores the best.
The Conti is a little less good in the wet. Michelin is a bit better in the wet.
Mark will be pleased to know his Goodyears did really well!
I think I will get the Bridgestones for my car.

I’ve had Bridgestones on few cars and haven’t been overly impressed with them,especially near end of life they become almost undrivable even with meat still left on them,pay your money take your pick,I’d even go for the Goodyears or hankooks over the BStone.Best car tyres to buy now: top tyres tested and reviewed | Auto Express

well yes, except the Goodyear that did so well in the Evo review was the Super Sport and I have the Asymmetric 6s
.Back to oil catch cans for a bit. I’m not that keen on the positioning of either the Airtec or the Forge ones as they are both tucked behind the battery in a very cramped space. Looking at the engine bay I don’t see why I couldn’t mount one over by the coolant, on the left - any reason you guys can think of not to do this?
I can make a bracket for the catch can and it’s only a couple of hoses to connect it up - I can buy the hoses, catch can and any connectors from AliExpress for about £100.00 (that’s for a fancy catch can - half that for ones like Airtec and Forge use). It looks like there is space under the brake reservoir and behind the engine for the hoses to go.

Hey, I recently ordered the SPEED Engineering kit on my LHD car. They use those exact two screws for the bracket. Looking at the RHD layout, the only noticeable difference is the brake reservoir nearby, but it doesn't seem to interfere with the mounting spot. So that spot should definitely work.
Hi,
Please let us know about your experience with the speed can.
Looks well designed, but I wonder if the 3d printed parts can endurance the multiple cold warm cycles over years.

Thank you very much for that info - extremely helpful
. In fact that whole kit will fit to a RHD car as well as a LHD one. I also see that Speed Engineering utilise part of the existing return piping and this makes installation quite a lot easier - a very good idea. Instead of replacing all the piping to the turbo they tap into the existing. The brake servo reservoir is just a neck and there is quite a lot of space directly beneath it so taking the pipes through there, and then behind the engine should be easy enough.
No problem! You’re actually lucky you asked now (with that picture) – Speed Engineering only released their kit last Friday. I’ve been looking for a catch can for a long time myself, but most options (like Forge or Airtec) are only designed for RHD behind the battery (and they state "only RHD" so I didn´t wanna try them really). When I saw those two screws you were pointing out, I immediately recognized them from my already studied Manual!
