Lightening front subframes...? Good Idea or Bad.
Turbo Mini Forums

Well I had an afternoon free this week.

And here are my results.







What do you think.?

Sorry for a photos being a bit out of focus. My hands were still a bit shaky after all that drilling.

Also seam welded tower tops and front mountings were the tie bars fit.

P.S. Not weighed it yet mind. But it feels a fair bit lighter.

I drill holes in everything..!

and i thought mine was looking a bit swiss!

It'll have to do for now.

Maybe one day I could afford a nice shiny Titanium one.

When's the next Force Racing sale on..?

I love the way you have made the holes in the towers bigger, very neat. I had to look twice to see what you had done. I need to do something like this at some point.

A man without a project is like a like a woman without a shopping list.

really theres alot that can be lost from the front frame, lots of holes & seam weld it, add some triangulation bits here n there, may have a bash at this

Ben H- Yeah, I gave it a whole lot of looking at before I got stuck in. worked out quite nice.

I tried to leave all the double skin areas alone. But thought everything else was fair game. Kept everything in symmetry to,to try and help with any stress which might occur.

If I ever was to convert to coilovers, you could probably take a bit more out of the towers, I think.

Matty- It's at the shot blasters at the mo. When it gets back i'll do a weigh in. And I have a clean standard subframe to compare.

clubminiflip - Help yourself mate. Thats whats this forum all about. Is it not.?

it looks very good but how much lighter is it?

no longer a series, but still 1.3 turbo.

do yourself a favour and enlarge the driveshaft holes too

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

did you ever weigh this?

Sorry I never got round to weighing it in the end.

But, It was much lighter compared to the standard one that came of off.

Sorry for not a more accurate measurement.

But all I can say is it was worth the effort.

i can measure and get pictures of mine when i can finnaly get back into the garage. unsure when thats going to be though!!

how many holes and what diameter,

you can work out the weight.

Loads and it'll be a bugger to get at now as theres a bloody engine in the way.

I wish I'd weighed it first. But I needed the car mobile. And pot_dan needed a front subframe for his a.s.a.p. So it was a quick change over job.

Looking at it again in the pic's. I could have easily taken even more out of it I recon..?

O well the next one will have.

had a bit of a sesh with the holesaw today, kept it quite conservative as im not after every ounce just yet:











didnt have any scales handy at the garage, but collected all the bits as a rough guide:



591g's, so prob just over 600g's removed

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

looking good!

actually i'm suprised it was that little.

cheers, me too, i was hoping it would be about 2 stone haha

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

i would have guesed just over a kilo.

I got just under 3kg off mine.....keep going guys

Paul

I seriously doubt it!

That's scary Paul! I guess there are no pics.....

No pics james. I run it for 4 years like that - no issues. Its not on the car anymore though, Ive gone 6.5kg lighter still.

Paul

I seriously doubt it!

Paul, so a total of 9.5kg lighter than a stock front frame, thats got to be titanium then?
