FRONT SUSPENSION
1. Remove the front wipers by popping the nut covers off and then un-doing the nuts (16mm) Then wiggle the wipers untill they come off. Mark where the wipers sit before disturbing them as the parallel linkage is slightly fiddly to set up again.

2. Remove the plastic scuttle.
a) Firstly remove the foam on the drivers side then the windscreen trims (about 4inchs long) running up the sides of the windscreen they are clipped in so be carefull not to break the clips. Inserting a small screwdriver in the hole will unlatch the lower clip from the scuttle

b) Also there are 2 round clips that you remove with a flat head screw drive just below the windscreen trims (I just used my fingers to unscrew them). then lastly 3x T20 torx screws that will then let you remove the plastic scruttle.

c) Theres a load of clips that hold the scuttle against the windscreen, so don't go trying to prize up the rear edge

d) Lift the front edge of the scuttle panel, infront of the wiper spindles. The front edge can then be lifted clear of the dish on the drivers side which is fixed. Once it's all lifted clear pull it forwards to clear the windscreen clips and lift it off the wiper spindles

3. Undo top mount but leave it done up finger tight as this will support the strut untill your ready to remove it(21mm and T40 to hold the middle if required). Here shows it dismantled but leave if finger tight untill later. Do not remove the second nut which was hidden by the tophat. That keeps the spring and bearing in place on the damper

4. Jack the car up and undo the wheel nuts to remove the wheels (17mm). On 133s, you will need both sides up, otherwise there will be a lot of tension in the anti-roll bar.

5. Removing the strut assembly. 1x ARB droplink nut. 2x Large bolts through hub carrier, 1x ABS cable
a) Unclip the ABS wire from the shock absorber bracket

b)Undo the ARB droplink (Not applicable to 1.2s) 16mm nut and T20 torx bit

Note:- Get a jack or some blocks of wood ready to support the hub assembly once you disconnect the strut in the next step. As, when its un-supported, the hub assembly can move sufficiently to put strain on the driveshaft and maybe pull the shaft from the gearbox... Using a jack to take the strain of the lower arm (+ drive shaft, hub, disc brake and caliper) helps to take some of the strain out the 21mm bolts when removing, and is especially helpful when trying to get everything lined back up when putting it all back together!

c) Then remove the 2 nuts (21mm) You will need to hit the bolts with a hammer to get them out as they are splined into the holes for a good fit. Note:- when you hammer out the 21mm bolts (because they are splined) it is best practice to leave the nut just on the end of the bolt to hit the hammer against. If you hit a hammer directly onto the bolt you will most likely damage/bend the threads and have trouble when re-assembling! Older cars will suffer more for this as the bolt become more seized.


d) Take the weight of the strut and completely unscrew the nut in the engine bay. Now, the strut should lift out.


6. Clamp the suspension spring up with spring compressors BEFORE REMOVING THE SPRING CARRIER TOP NUT. Theres no need to go mad, just untill the spring is slightly loose.
a) undo the (27mm) top nut whilst holding the rod with a T40 bit.

b) remove:- nut, rubber bush, bearing (note which way up this goes), top spring plate

c) Once you have done this you will then be able to remove the spring but be carefull when un-compressing the spring as it will be under alot of tension and can take your head off !!!!!!!!!!!!


7. Re-assemble the top spring platform and top mount in the order they were removed, making sure the tails of the spring seat into the dips of the platforms

8. Re-assemble everything in the reverse of removal.



REAR SUSPENSION

1. Remove the lower shock bolts (18mm) with the wheels still on the ground

2. Jack the rear of the car up. Doing both sides at once will allow the axle to droop and the springs can be removed without a fight. If you only do one side at a time, you will be fighting against the torsion of the axle. It can be done but you will need to compress the springs a bit. ;)

3. Remove springs and mounting bushes, then unscrew the bushes from the spring

4. Screw the bushes onto the new spring untill the tail of the spring is against the stop. The rubber nipple on the lower mount pushes into a hole in the the rear of the axle.

5. Slowly lower back down, making sure the springs/bushes and bumpstop are seated correctly once they start to compress.

6. Rebolt lower shockabsorber bolts

7. You now have a lowered 133 (1.2, GT)

Hope i havent missed anythink but please plese take care when doing it yourself as it in very dangous.
 
fook that lol, i'll pay a garage to do mine!!! :shock:

good guide though for the mechanically minded / brave!! :cool:

If your not mechanicaly minded, swapping out springs may not be the best introduction. It's not difficult as such, but by the time you have bought tools, axle stands,etc, the difference in cost between a garage fitting them ( ~£150 +tracking adjustment ) and DIY would make the garage route an easier option.
 
Some people insist that you should get a full geometry check and corner weighted after altering the ride height. Whilst i agree, there isn't much that could be rectified without fitting after market adjustable strut tops or excentric camber adjustment bolts on the front. Theres even less point for the rear axle.


Front axle Toe angle (Steering tracking angle) can and should be adjusted but that is about it!

Yes, you could slacken the subframe and move the subframe about complete with the Track Control Arms to equalise camber angles between each side, although lowering wouldn't affect the side to side imbalance as this is realy something to do after an accident. Moving the subframe could also be used to bring the caster angle back in, as this will have increased due to lowering but not unduly with a 25-30mm drop. However, short of a specialist motorsport prep garage, your not going to find many places willing or able to do that.

The rear axle is a beam design, which will have a certain amount of camber/toe change versus ride height built into it. However, barring accident damage, bending the axle, there shouldn't be much to cause to check and move the whole axle relative to the body as theres no adjustment possible at the wheels.



Corner weighted on springs :? By corner weighted, I assume they mean getting the corner loading adjusted, rather than just weighed for shits and giggles. Yes it's possible by shimming the strut top mount but is this realy viable with lowering springs as that requires re-stripping the struts again to add the shims. A track car on Coilovers, maybe but it's not essential for a road car.
 
who's got some pictures with before and after lowering ?

(or is there a topic about this ? )
 
I have seen the APEX kit
Lowering 25 mm for Twingo RS
Ref. 150.5210

But they do not explainif it's for Sport or Cup chassis ?

Will they fit the Cup or Std ?

They will fit both Cup chassis and non cup (sport) chassis.
 
Tada!!!

Successfully lowered twingo using this 'how to'
Did it myself with the aid of a friend and spring compressors bought for £10

Just how I wanted it to look! Cheers :D
 
Cheers guys :D had a drive on some country roads earlier and wow! So much for fun, I now enjoy sticking to the road like shit to a blanket :D
God damn I wish I had a CUP!
 
Only difference I noticed, is that the bolt you are undoing on 5B.. On my car there wasn't any kind of bracket like on yours, just the two large bolts and it was off! Was really simple, just the springs were abit awkward :p
