Front Chassis Rails on Mk2.5

Postby kpdornan » Wed Aug 17, 2016 12:40 pm

Dear all and especially owners of mk2.5.

Have recently checked under the engine tray on my 2003 mk2.5

The amount of corrosion on the front chassis rails is frightening.

I would advise everyone to have a look as soon as possible as it's never going to get better, only worse.

MX5 restorer has the repair parts for approx. £140.
Only good I would guess as long as you have enough good metal left to fix.

I will be having my car at Ramp It Up in Arbroath for a couple of days at the end of the month to:

1/ learn how to remove all the required parts before the next days welding
2/ have my fingers crossed that all the bolts behave, I see a lot of plus gas being used over the next week or so in prep
3/ underseal the life out of everything before driving away happy, I hope

Any thoughts or advice anyone can offer would be greatly appreciated.

regards

Kevin

My advice would be to budget extra time, just in case...oh and keep cutting the rotten stuff away until you get to solid metal. You can always get the whole chassis beam assy complete if necessary.

I had a similar issue a few months ago, see my thread here.

There are two places to get the repair panels.

The one you mentioned that do an L shaped panel outside face and underside panel and as an extra a mini inside face.

Wayne on the Mazda Menders board does a U shaped panel that is outside, underside and inside face in one panel. Similar price if I remember.

The guy at Ramp up can mig weld and he also has access to a very good fabricator welder if he considers it beyond him but I rate his welding ability.

Thanks both.

Neil is getting his welder from Aberdeen down to do the job on the Saturday.

Hopefully I can get it prepped on the Friday.

To be honest any welder will probaly re prep it because the just do!

What time is he starting on Wednesday as I may well come down and get some tips for doing it myself or not after I watch him.

I have got the two long bolts for wishbone and nuts for when the original ones won't come out. Which other ones would be recommended to have in case of rusted parts. Getting confused with adjustment bolts camber bolts etc.

Thanks

The camber adjustment bolts can be handy, MX5parts have them.

If I turn up I will bring some camber adjusting bolts with me.

Thanks Eddie,

What about the bolts that fix the bottom end of the shocks?

Toying with the idea of doing the bushes at the same time since Neil has a 20 ton press, seems like common sense.

hi Eddie,

turns out neils welder won't be doing job now.

Neil will be doing the welding so not sure if it would be done Friday or Saturday.

Just thought I would let you know since you said you might come down on the Saturday to watch.
Maybe check with Neil?

regards

Not a problem and I have seen Neil's welding and it is good quality.

Job done, pictures to follow soon once I master how to.

Car now structurally sound, brilliant job by Neil at Ramp It Up in Arbroath.

I would recommend him to anyone.

Yes, I went down to the job on Saturday when one side had been done and great job done at Neil's.

It's getting to the point where this is the just one of the jobs that has to be done in the life of a Mk2/Mk2.5.
