Mk1 MR2 Hubs
ChrisJLW - 29/7/04 at 08:31 AM

Anyone used the hubs off a Mk1 MR2 for their Locost build?

Thinking about suspension fitment more than anything, would they convert relatively easily to the double wishbone specified in Rons book or would it require some pretty serious chopping and welding.

Hi, Im using them on my Mid Engine build, I havent got as far as building the chassis/wishbones yet; but the bottom ball joints attach to the hubs, and you would need to fabricate something to bolt to the top of the upright as it mounts directly to the shock on an MR2. There are some pics on Allan B's Site (http://www.desicodesign.com/meerkat/Donor%20parts.htm) if you want any specific pics/measurements, U2U me, i have the hubs kicking arround at home.

You will need to make an upper balljoint to strut adapter. The balljoint being used is an early 80's AMC Eagle upper front. This was when AMC and Renault were buddy-buddy so you may find a Renault part that works but I can't verify that. I do know that the old Formula fords were doing something similar some years ago so it is a tried and proven method.

Alan B. (Meerkat) really paved the way for me to do this suspension. He custom made his adapters of plate steel (Lots of great photos on his website). I made mine by cutting the original MR2 Macphereson strut tube down and welding a plate to the top of it. The balljoint bolts to this plate.

Some people would say that the MR2 Hub/lower balljoint is strong enough to support the weight of the car from the lower balljoint like a standard locost suspension. Fearing serious injury or death, I made the decision to use a pullrod attached to the upper arm so that the weight of the car is routed into the hub like it was designed for. I would rather not find out under what stress the lower BJ breaks, because it would probably be at a very critical moment....

Here is a photo of my Adapter.


And a photo of how it all fits together

Cheers Monkeyhunter & Graber, that's another set of bits I can use off my old Mk1 MR2. I've got a really nice set of lightweight (if somewhat battered) alloys that I can use off it as well.

I think both of the above are describing mid engine cars where they are designing the steering to suit.

Do the hubs have a steering arm at the front of hub as Cortina, this will fit a standard Locost.

Just a thought.

Steering arms are at the rear of the hubs, will have to have a play once I've got them off the car.

Don't suppose I could use the left hub on the right side and visa-versa

Steering arms are indeed at the back. Sorry I didn't realize the question was posed for a standard Locost build. (Must practice reading comprehension...) IMHO using the MR2 hubs in ths scenario leaves you with 2 options. Make it a BEC or Rotary powered car because these engines are shorter and fit further back, or move the engine to the back and build a... wait for it.... MIDDY!!!!! Yeaahhhhh!

Bet you can't guess which option I would choose... LOL

Well I have been toying with the idea of a Stryker 2 kit, but my neighbour has all the steel for a Locost chassis ready cut in his shed. I think he only wants about £70 for it.
