compact raod rally

Postby compact119 » Sat Sep 05, 2009 5:00 pm

right then i thought i had better do a thread for my road rally car, 318ti M42
its work in progress but aiming to be finished towards the end of the year i am wonting my first event in this car to be the telford novice rally

so far i have fitted offset control arm bushed (e30 M3)
Image
offset front front strut tops (e36 M3 evo) well complete struts, when fitting these i found it gave loads of positive camber (due to lack of weight in my compact compeared to the M3) so i first tried some camber correction bolts but that didnt give me enough negative camber so out came the die grinder. once i had achived correct camber i welded the washers in place to stop them moving. its very handy working a bmw dealer as i was able to pop the car on the four wheel aligment ramp and make sure all was well and its all in spec :D
Image
next job was the exhaust, it was starting to rote on the back box and i wonted to take the cat out as well. very happy with the end result which should pass noise fingers crossed. took a lot of weight off the exhaust too with only using a center section from a 123D as the back box and a E90 320d center section in place of the cat.
Image
my next issure was a LSD, after lots of sertching and resertching i wasnt happy with the prospect of buying a LSD out of a 325 for example that had covered lots of miles and probbly not that effective anymore so would need to be rebuilt and if ur doing that u may aswell do the atles conversion to it and all of which was starting to make my road rally car become very exspensive. so i thought bugger it and found a 4.4 ratio diff (still small case from a 318 auto) so i had the right ratio. before fitting the 4.4 i welded up the diff thats in the car allready as a bit of an experiment (with most ppl laughing saying it would push on through corners and so on) which i am very happy with so i think i got the last laugh as it handles mint and it was free to do and all i need to do now is fit my 4.4 and jobs a fish as far as the diff is concerd

after some playing with my newly welded diff i seen to have broken both engine mounts hhhhhhhhmmmmmmm i woulder how that could of happend haha :twisted: so i got on the phone to a mister harry hockly seek his advice on compertion enginemounts and came up with a plane wich consisted of me paying some money and waiting :D also orderd a sump gaurd. the engine mounts wernt as straight forward as i fisrst thought they would be and required some mods to the sumbframe . very happy again with the end result and a bonuce is that the engine has been lowed by 20 mm in the engine bay wich can only be a good thing :lol:

Good stuff compact119. 8)

Not sure about the welded diff, mind. :shock:

Did you try swapping the topmounts left to right to sort the camber issue?

lol the welded diff is megga :evil:

as for the engine mounts i am sure that if u gave mister hockly a call he could supply them not sure if these or just what he had left over from a build or not i can give him a call and find out ??

the struts were fitted as the came off the car as they were labled

next is the sump gaurd fitting so a frame will need to be made between the chassi legs and some sort of hanger at the back under the gearbox. i have a few ideas of how to achive this but any sugestions are very welcome. aiming to do this next saterday :D

thanks for the comments :mrgreen:

Thety're fitted the correct way around, swapping them over shifts the topmount inwards and gives some negative camber.

Mine are swapped across compact119 and (IIRC) it has 0.5 - 1.25 degrees of neg camber through the ride height range. (Adjustable height coil overs.)

Sump guard is chassis rail mounted F&R with a brace across the front and the OE X-brace bracketed as a centre support.

as this car is my day 2 day car driving it around the last few days since i fitted the engine mounts with the engine in its lower position. the differance it has made is briliant i supose when you move the haviest part of the car up or down its going to have a big impact on how the car drives. very happy :D
