i think the lower ride height you have there is the better choice, the first tall one would be what youd have if you threw 4wd suspension under it.

my dad has a mk2 2door sitting in the front yard, floor is all cut out and been replaced with full custom chassis and cage work. > even stock, was lower than your first height lol. keep it up, cant wait to see what you do with the front suspension.

Yes the lower looks much better! The first pic is more what it will look like at full droop when wheelw are off the ground in rally mode. I plan to have the sitting height a tad higher than the second pic for all around rougher terrain but I'll have it adjustable anyway so I can also slam it to the ground edit: I think the suspension travel limit will mostly be the body, more than the frame. At some point the tires will rub in the wheel arches! But the car will still not bottom out.

Cant wait to do the front either !

This one is with the fake tall sidewall rims and smaller diameter tires, makes for a more stock look. In this pic it is approximately 5mm ground clearance. Given these tires have +3mm offset they start rubbing in the fenders at that height but they still fit nicely. I am glad they do because I think they look pretty scale.



The smaller tires/wheels looks more appropriate for the escort IMHO, compared to the normal wheels and tires (same pic I posted previously):



And the 2 piece adjustable offset wheels, 31mm wide rear (wheels are in +2mm position):

Here are pictures of 1:1 aftermarket (modded for rally) escort front suspension. See how the lower arm is actually two pieces, one is the main arm (a link with two ball ends really) and there is a second link to locate the arm and prevent fore-aft movement.






I think the production Escort MK2 had similar main arm link, but the secondary link served a double purpose as it was also the sway bar (if I understand the pics correctly).







I think I am going to do the modded version, and have the sway bar separate, as it will be easier to dial in the suspension. To start with I am not going to put sway bars, at least not right from the start. It looks like people are modding it to simply replace the sway bar attachment by a link attached to the chassis.

Hey Frederik that looks pretty cool! Hope you can pull it off!
The production MK2 had a trac-arm ( main suspension) and a stabilizer bar as in the 3rd pic!

Great, thanks for the input! So it does act as a sway bar and hold the main arm at the same time? That's an interesting setup.

Yep if I remember correctly, the trac-arm connects and pivots off of the cross-member that's below the engine. The other end of the trac-arm has the ball joint that the strut bolts to. Then the sta-bar is connected to the trac-arm and the steering rack tie rods are connected to the spindle assembly on the strut.

Thanks again for the input. I was still unsure if the stabilizer bar was really a one piece bar or split in the middle for independent effect. Thanks for clarifying.


Here are the 21mm wide tires I have bought for the steelies rims. Should fit well with the wheels for that stocker look:



And the drift tires and wheels I have ordered too, I have a feeling that car will make for a pretty cool drifter




And a couple 1:1 pics just for kicks

Made a first draft of the front strut design. Still a lot to sort out:

I made the steering part way too big and it would interfere with the frame. It will have to be higher or lower than the frame rails throughout the suspension travel.

I still need to add 3 or 4 screws to sandwitch the two outer aluminum pieces. In the middle, the thinner L shaped part holding the shock also serves as the retainer part for the bearings. The two outer pieces are drilled through size of the bearing, and the thinner center part is smaller.









Also I can see the lower suspension arm is going to be very short, almost like two of these ball joints screwed onto each other. This will make it hard to make the secondary arm like the actual car and attach it to the arm. Maybe I will put the mounting holes more towards center of the car. I am having other ideas as I write though Nothing unsolvable I think

Thanks for the comments guys! I think I will just cut the steering arm part on the knuckle and bolt the newly shaped one on, instead of making a whole new knucke "half".

I am having some issues receiving my gd-600 gearbox from rcboyz on ebay... After a month I finally received the wrong item (some aiplane mini brushless motor) and now its been a month since they said they shipped out the right item and I still havent received it... I order stuff on ebay from hong kong, UK and almost anywhere else in the world and it is never as long as this, and it is a USA based place, dont know what is wrong with their shipping methods. /end rant lol

Wow! That's rough bro! I have bought parts from rcboys before and the order usually shows up in a few days ! However I haven't bought anything from them within the last 6 months so maybe things have changed...
Anywho... Would you happen to have an exploded pic showing the individual parts of your front strut? I really like your design and will like to replicate it if that's ok with you.

That would be perfectly ok with me! In fact I'll be glad if you use anythhing from my build! Here are a few more pics I just snapped.

There are 4 main layers from left to right in the first pic:
-The inner bearing and ball joint holder
-the strut support (angled for approximately 100 degrees strut inclination)
-a shim because the strut support is not thick enough to fill the space between the two bearingson the axle shaft
-the outer bearing holder and steering support.

Keep in mind I still need to put screws (4 probably, one at each corner) to keep the 4 layers sandwitched together.

I will likely have to put the screw heads towards the inside, so I dont have the screw heads poking out where the wheel mounts. That means I will drill and tap the outer bearing holder and use screws just the right lenght so they end flush with the outer bearing holder.

Still needs to do somehing about the steering arm which is way too big, but you get the idea.
