Hi everybody!

Me and two friends of mine started a team called Magnus Racing a few years ago, now it's time to make it more official.
We lived in the same city in Finland and we still have our garages down there. Everyone has their own car to build, aim is to go faster without looking bad.

Like us on Facebook to see those other projects and more updates:

This thread is for my BMW E30 built to streetlegal TimeAttack racer.

Everything started from this, orginal BMW 320i 1987:
http://i187.photobucket.com/albums/x281/mice325/keskuvaa005.jpg

In few months I had bought and done a lot of stuff and car looked like this:
18" wheels                                   http://i187.photobucket.com/albums/x281 … asa007.jpg
D2 coilovers and 325i disc brakes  http://i187.photobucket.com/albums/x281 … aan011.jpg
Headers                                        http://i187.photobucket.com/albums/x281 … C03164.jpg

Powerflex bushes                          http://i187.photobucket.com/albums/x281 … saa006.jpg
Sparco seat and Momo wheel        http://i187.photobucket.com/albums/x281 … taa002.jpg

By that time I had made all the chassis work to make it rust free, good subject to start a bigger project.

BMW was hold in the garage for few years and I only scraped some stuff together:
M30 engine                                  http://i187.photobucket.com/albums/x281 … rsu007.jpg
E36 M3 spindles                           http://i187.photobucket.com/albums/x281 … uva141.jpg
Had a cheap coilover kit                http://i187.photobucket.com/albums/x281 … s09009.jpg
E34 M5 rear axle                          http://i187.photobucket.com/albums/x281 … G_4774.jpg

Recent years I've done more or less, at least I've tried wink

Got BBS RF wheel centres today, they're from 8x17" ET40 wheel:
http://i187.photobucket.com/albums/x281/mice325/wheelcentres_zps1af3a21d.jpg

Fitted them to my friend's car which has 325mm discs with Wilwood Superlite calipers, needed 15mm spacer to fit.
I'm planning to buy same discs (E46 M3) and Cayenne/Touareg 6-piston calipers in front. There won't be too much space:
http://i187.photobucket.com/albums/x281/mice325/IMG_6618_zps62b8e3ed.jpg


Also made little room to rear seat area so I can make the new shock towers.

Tack! smile

I had to make more room for the rear axle as it didn't fit as high as I wanted, next step is to modify body beams if that's not enough.
Otherwise there would be problems with trailing arm and output shaft angles with desired drive height.

New plate allowing even more lift of the axle if needed, now there's about 4cm space above the carrier:

Today postman brought this quick release/snap off hub for steering wheel, it would have been very hard to climb in and out of the car when the rollcage is finished with the door X-brace.

Now I'm waiting my custom K-Sport coilover kit, it's based on the Circuit -model, but customized at the factory to my needs.
Front coilovers are E36 M3 type and rears E34 type which are a lot shorter than E36 or E30 shock.
They should arrive soon.. tongue

Coilover order came today, thanks for K-Sport Finland for an easy and fast transaction!

Looking good cool

I need to design topmounts to the front with 4-bolt fastening, which allows me to make caster adjustment into the chassis. Also rear end topmounts need a little bit of modifying, thinking of spherical bearing instead of solid mounting.

Now I got all the parts to finish the rollcage, lot's of work on the way!

Started with the front end last weekend, now it starts to take form.

This was the beginning, only showing approximate location of the top:
http://i187.photobucket.com/albums/x281 … 1746c7.jpg

Took this picture today, other half almost ready:

And another:

Placing of the roll cage tube:

Also made a 3D model of the front top mount, just needs to be machined:

Started with the rear end, but ended up to cut a lot metal off.. Pics coming soon.

Designing the shock tower:

Finally found the brake calipers in affordable price. Porsche Cayenne Brembos 6- and 4-piston calipers:

And E46 M3 front discs:

Time for a little update.

Worked with the rear end a couple of days, lots of cutting and welding new structure.
Axle is now 5cm higher than orginal mounts would allow, that should be enough. Only little sheet metal work to do.

Looking empty, again:

Massive brakes? Guess does the caliper fit with the E36 king pin? Nope, needs "a little" modification too roll

Here comes the update part:

Not much progress with the car last days due to working all day, but I have to try this week. And next week we'll go to Gatebil Mantorp, as usual  cool

But, I've done little modeling and measuring in my 'billet steel rocker arm' project. Bought a new orginal rocker arm and got it measured at job.
http://i187.photobucket.com/albums/x281/mice325/IMG_1275_zps86088fa4.jpg

Maybe we'll get something like this:

Also bought a new fuel cell, 60liter JAZ, which will be placed just about down there:

Wasn't satisfied of the rear seat area design I made earlier, so I made it again and it became much better I think. Looks a bit more orginal and more simple:

Some slot to be welded:

Also got shock towers and half of the inner wheel archs done:

Some welding.. What do you think? Not much experience, but I think it's good enough:
http://i187.photobucket.com/albums/x281/mice325/WP_001543_zps98374d2b.jpg

Decided to put a pair of extra pipes to the cage:

Next week should be more productive, I dream of finishing the rollcage, we'll see cool
