hope we can make this in to a sticky to be put in the mk3 maintenance + info section :)
i have seen many post on here for lowering a mk3 , also many members have had there mk3 slammed basically can you all post what kits you used and what parts are needed also links and kit costs ?
cheers
Also need to get mine done !!!! ;)
-
This is a good idea....everyone list the kit they used, price and verdict. Could be useful in the future as i plan to lower mine.
-
The usual lowering questions are about how low, what wheel/tyre combo etc.
So a how to guide plus useful tips would be a good idea. Like the top swivel mounts.
-
Very GOOD idea! :smiley:
-
So who has done it and would be prepared to do a write up?
-
I put this on another site its a bit basic/crude its party hijack from a book i have and not the best written but thought id put it up
I will give some info facts and stats, and different types of lowering, guides etc.
The main reason why we lower cars is it looks a lot better, standerd suspention is usully always to soft as it made for a wide range of markets, and its always to high.
Lowering a car should improve handling if done correctly, it lowers the cars centre of gravity closer to its roll and pitch centres, which help it to stick to the road in the corners and under braking, with stiffer springs and shocks reduces body roll and increases the tyre contact on the road, a handling improvment is only achieved to a point, if the cheap route is used its not always what you will get, i.e just springs, or extreme lowering.
it can be very hard to guess the amount of drop you can achieve its best to do as much measurements as possible to avoid burning / bumping rubber or scraping, most cars take up to 40mm drop with no problems at all its over 60 where the problems start but can be solved by arch rolling spacers etc.
as you are proberly aware most french cars( citreon peugeot etc) have a rear torsion bar setup on the rear, which uses very strong steel bars the steal bars are spindled at each end, and they link the trailing arm to the opposite end of the axle cross member and the behind it, very confusing i know. These steal bars twist as the suspention moves up and down throughout all of its travel and its the cars resistence to the twisting which make the springing of suspention another steal bar passes through the centre of the rear axle crossmember and like the trainling arm both of them, this is the anti-roll bar ,which is stiffer than the other two, but still function on same concept of others.
to reset the height is a very involved task, not difficult or dangerous but very fiddily, on older cars may be very diffcult as cars could have rusted parts , the positive of torsion bars is you only pay for labour of doing no new springs to buy
to adjust it involves removing torsion bars, setting both rear trailing arms to desired height, reinserting bars and ensuring the split lines are put back correctly, not easy its best get it done profesionally
These are the setups you can have
UPRATED LOWERING SPRINGS ON ORIGINAL DAMPERS
PROS: This is very cheap you will get lowered look, and can mildly improve handerling
NEGS: handling can be destroyed, as there designed for matched dampers so lenth of dampers is greater on normal dampers dif rates etc characteristics, can give bouncy poorly absorbed bumps etc
always buy progressively wound springs for smoother ride and cope with big bumps and extreme cornering, only use drop between 20-40 mm on standerd dampers or handerling wil be rubbish any lower, personaly i think its a false economy to buy just springs
THERE is hydrolic suspention but dont know much about it apart from better ride and adjustability and its sky high prices to buy
UPRATED SPRINGS AND DAMPERS KITS=
FOR: You get a massive handling improvement, due to it being well developed, some shocks even have adjustable damping to adjust to your preferance, The ride will be more controlled and a lot less bouncy than not modded suspention or just uprated springs,
NEGS: there is always a compromise in life and its no different here due to the incresaed damping spring rates the ride may be quite harsh, as it is well developed and controls handling well, id recommend this option on a budjet but want good handling, coilover are always best but should be for the price
A FULL KIT IS A GENUNIE UPGRADE, WITH A WELL SORTED CONVERSION YOU WILL GET REQUIRED DROP AND STILL RETAIN PREDICTABLE HANDLING CHARACTERISTICS, DEFINATLY A MUST IF YOU LIKE TO PUSH HARD ON THE ROAD, WITH A MATCHED SET OF SPRINGS DAMPERS IS ASSURED TO IMPROVE HANDLING AND RIDE QUALITY SHOULD BE SMOOTH YET TAUT, BUT HARD ALSO.
COILOVER:
PROS: ride height can be changed usully between 20-80 mm more expensive ones even moredamping can be set to prevent bump scrub and can be set up for amazing handling, or slammed for shows
NEGS: the are very expensive up to £2000 most start at 400-600 and hard to set up too, ride is seriously hard
COILOVER ARE THE BEST,A ND THE CHOICE IF YOUR NOT PREPARED TO COMPREMISE, IT COSTS A LOT BUT YOUR GET WHAT YOU PAY FOR, IT OFFER ONE FEATURE OTHERs DONT TRUE ADJUSTABLE RIDE HEIGHT AND DAMPING ADJUSTMENT, CAN MAKE FINE TWEAKS, EASY SCOPE TO FIT BIG RIMS, THEY ARE BASICLY AND IMPROVED SPRING AND DAMPER KIT WITH HUGE ADJUSTABILITY.
SUSPENTION FACTS/INFO:
CIRCLIP= ITS IS A FLAT STEEL STEEL SPLIT WASHER, IT FITS INTO THE GROOVEON THE BODY OF DAMPER, ON WHICH THE SPRING CUPS SIT.
BUMP SCRUB= THIS OCCURS WHEN THERE IS TO MUCH COMPRESION FROM THE SUSPENTION, GOING OVER A BUMP, THE WHEEL IS FORCED UP AS SUSPENTION COMPRESSES, SCRUBBING THE WHEEL ARCH
DAMPING /SHOCKS=DAMPER ABSORB SKINETIC ENERGY OF SPRING STOPPING FURTHER THE REACTION OF THE SPRING, DAMPERS STOP THE CAR BOUNCING ALONG THE ROAD HENCE WHY IT DOES IF THE DAMPERS ARE SHOT
PROGRESSIVELY WOUND = ON THESE SPRINGS HAV EBEEN WOUND CLOSER AT ONE END THIS OFFER A RACE CAR FEEL PERFORMANCE WITHOU AFFECTS STANDERED RIDE HEIGHT MUCH
SPRING RATE= IS THE POTENTIAL RESISTANCE AGAINST COMPRESION OF THE SPRING, MEASURED IN POUNDS A LOW SPRING RATE MEANS IT HAS A LOWER POUNDAGE AND IS SOFTER
TO avoid problems with car after wards after any setups of suspention , i advise full geometery setup and check, and cambers tracking etc un les you want cronic tyre wear on edges or inners and stodgy handling. Your geomety wil be changed affected more of a problem the lower you go, so get it checked straight after its lowered
-
think mines too low the mechanic said it occasionally hit othe rparts or driveshafts not sure how but nearly the max on fk coilovers, maybe about 10mm left
its seriously taut, and boucy on some roads, but glides around corners just a sham eits got a tooth chipping ride due to poor uk roads and can get very jarring at times grr
but still damps ok on better roads
i guess mine bad as its a bit to low so doesnt handle perfect on bumpy roads dips etc, i think 40-50 mm is best compromise, and no more than 40 mm on standard dampers with just lowered springs as it fooks handling up im told
-
All very good and informative mate but I believe the intention was to do an actual how to do it guide, the nuts and bolts bit and fitting them!
-
I know, i just thought id add it, be good if someone shows the acual process stage by stage as you say
-
ok this looks like a job for me... I will start a new thread with fitting, recomendations and usefull info
anybody want to post some pics of there motors before and after with what's was fitted etc and i will crack on!! and I will move your pictures and details at some point??
-
ok I've knocked a quick guide up here http://www.golfgtiforum.co.uk/index.php?topic=68845.new#new (http://www.golfgtiforum.co.uk/index.php?topic=68845.new#new)
anything else that needs adding please post here and i will move accross... pictures with coilovers etc needed
-
Looks :cool: well impressed!
-
Im one to agree with the proposal of a lowerin advice sticky, After having major problems with mine! top mount issues to list one....
A sticky such as this would have saved me alot of money and walking! ha :grin:
-
:) thank you for all the info !!! very nice to have a guide :) cheers brad :)
-
Top marks Mr. Bradley!
That guide and links might spur me on to do mine! :grin:
-
right im just back from a run in my new dub , the back left arch is scrapping , and im needing new sussies , i dont no wat original height the car should be at, so if i go and buy some sports damperners and sports springs what size of springs should i get , i dont want the car 2 be raceing deecked out style , im 2 old for that :cry:
-
also i have a set of golf gti mk2 spax sports damperners , will these fit a mk3
