E30 318is help needed coilovers

[Brendy318is]

Hi, have bought my first e30 318is and was told they have 45mm struts but after research ive found out they are 51mm struts and I have a set of bc coilovers 45mm brand new and would like to fit and use these as I spent good money on them and was recommend them, if I buy full 45mm struts and weld the coilovers in will I be able to swap the brakes etc of the 51mm strut into the 45mm uprights after coilovers are installed? Thanks any help appreciated

All the coiloverz expertz are on the facebook page

Why would you want to downgrade your struts for the sake of coiloverzz?

Sell them to some stance type (most have lower models so the smaller struts are well suited to them) and buy some 51mm versions. Alternatively, have you tried contacting BC? They were very helpful for my friend. Explain you ordered the wrong size in error and see if you can swap them.

If you do all of the above you'll destroy your car. Better bet is to sell the coilovers, and invest in a set of Bilsteins and H&R or Eibach springs along with some M3 eccentric wishbone bushes and a general freshen up of all the other bushes. This will make your car drive and handle really nicely.

Using 45mm coilovers will make it drive like a turd.

What about the lowz and the gape ?

[jimbom30cab]

no idea what you're talking about Pete

[Brendy318is]

I was sold these "bc racing coilovers" as being track coilovers they have damping and rebounds setting both front and rear they aren't Sapost to go that low more for handling spent close to 1000 on them so wanted to give them a shot atleast, maybe contacting bc would be best bet

[ross_jsy]

If you have bought them brand new, it's a no brainer.

[Brendy318is]

Yeah had them 5 6 months tho hopefully they'll swap them
Over cheers

Sorry to thread jack but what do the M3 eccentric bushes do? I've missed this trick!

[M3Pete]

They move the wheel forward slightly and improve castor.
This helps the car to feel more stable at speed and improves the self centring properties of the front suspension.

Ok that's interesting! My "is" is running full polybush, Bilstien B4's, purple rack and new toyo tyres but I think it still feels a little wandering at high speed, like the weight is coming off the front as the speed increases. My old e36 M3 always felt like it was on tiptoes when it was really on it but still planted, the e30 doesn't give me the same secure feeling? Do you think these might help? Again sorry to OP, treat it like a free bump

[Cloggy Saint]

I had the M3 eccentric bushes for a while and they made no discernable difference whatsoever.

[ross_jsy]

I noticed a decent improvement on the 2 e30's I have fitted them to now.

[hillbilly30]

What was the improvement you noticed Ross? It's such an easy mod though, I guess I can't really go too far wrong

[ross_jsy]

Slightly improved turn in, but mainly how the steering self centres a lot better. My daily uses a quick rack from an Impreza with no power steering and before, the return to centre was very slow and would require lock to be manually wound off, which is a pain when letting the back end hang out. Now it's very natural in the way it returns

its like night and day! If you can't notice the difference well i'm severely shocked! tbh

Almost one of the best "mods" to an e30 of any kind
