I've been doing trackdays in my e46 M3 for several years now and have been DIY modifying it along the way. The chassis and aero have almost reached a point that I'm happy with, as I'm now approaching my goal of GT3 race car cornering speed. Here's a video from Monday's trackday at Silverstone, which had some incredible machinery in attendance (Carrera GT, Gunther Werks 911, DB4, 650 GT3 etc)

Looks like some serious cornering speeds there compared to the other on track. Looks planted as well fair play if you’ve set all that up yourself!

As a side note why do ultimas always seem so slow on any video Iv seen of them, I thought they where up there with fastest track day cars? Are they tricky to drive so people not confident to take to the limits?

That's a good question, I don't think I've ever seen more than a couple of ultimas on track in nearly 20yrs of trackdays.

Great looking aero on your M3 - credit where it's due.

As to Ultimas,
1. They are rare and
2. You have to look at why people build them and what they built them for.

I suspect the why is that they love the look of them and fancy having such a look-at-me car.
The other why is that it is a great challenge if you have the skills.

One came to a charity track day I did a few years ago at a live RAF base.
It didn't go on track, but spent the day with the clamshell up and people, including me, admiring it.
It was owned by a young RAF lad who built it because he fancied the challenge.
He actually admitted to me that he didn't enjoy driving it much - too awkward, too hot etc.

I suspect many didn't consider what they were going to do with it once built.

TVRs are not rare, there are thousands of them. I own one, so am likely to spot one on the road.
I have not seen one since the TVR track day a few months ago.

I built one years ago. TBH the build was much more of an experience than driving it. It was cramped and at 6'5" I barely fitted in it, and wearing a helmet my head was against the roof (actually the door!).

I only did one trackday, at Oulton on a dark damp November morning. It had no grip whatsoever, I think the rear tyres in particular had been sitting around for a while. I spun twice coming into corners, I think just a combination of plastic tyres and big torquey motor, maybe too much rear brake bias. No chance of catching it. I tippy toed round for a few sessions and drove it home. I suspect on a warm dry day it would have been a different experience.

It was fast, 500hp and about 1,000kg, but I never gained any confidence in its handling. Certainly my driving position was very compromised in it - OK for normal road driving but not for driving on or near the limit.
