E36 Compact Suspension

Postby doubleg » Mon Apr 28, 2014 9:29 am

Longer term on the other shell I'll maybe look to do something with coil overs but I wanted something off the shelf for the time being.

This is for the 318ti and for road rally use.

As it stands I was looking at
Front
Bilstein 35-233596
Bilstein 35-233602

Bilstein don't have a rate listed but have them down as a "Motorsport" shock absorber.

Rear
Bilstein 24-233637

Bilstein have this listed as 260/120; Length 533 mm and as a "Rallye" shock absorber.

They also state that you need BMW part number 31 33 2 228 345 which according to ETK is a E36 M3 top mount. Which strikes me as odd for the rear of the car.


I was planning on replacing the rear arms while we are on but probably leaving it with standard bushes (bearing in mind I intend to build up the 316i as a better built car with cage etc.) on the basis that as the arms are prone to bending anyway that the improved suspension is possible going to put more force through them?

Anyway I'm a little unsure what to go with spring wise, I was thinking just standard 323ti compact springs on the front but wasn't sure what to do on the back.

What are people running and finding the best option. Car will be road rallied so needs to be able to handle whites but not miles off the deck.

Standard height seems OK, decent enough clearance and we certainly haven't had issues with the 316 bottoming other than on rough whites which is pretty inevitable.

What kind of height did it sit at with those on the back Adam?

the car probably sat 20mm higher at the rear, we sometimes use the rubber spring pads to lower/ higher the rear slightly by adding or removing them

could you put a link up for the shocks listed above?

im looking for some front shocks for a road rally build, but not come up with a lot other than converting my struts to coilovers.

cheers

Hello there.
I have a 323 ti Compact as a ''Low Budget** rally car. I am mostly doing smal tarmac rally's and Rally sprints in Denmark.

I use the Escort Group 4 Bilstiens and standard HD compact springs rear :

http://www.ebay.co.uk/itm/Mk1-Mk2-Escor ... 232786a958

In the front i use the XYZ coil over shocks and iam not so satisfied with them so my next wish i Bilstiens MS schocks:
http://www.raceparts.cc/product_info.ph ... -vorn.html

I think they vil work great.
I use the M3 5 speed gearbox with 5:0 ratio in a 188 mm casing, that works very well with 16'' and 17''
tyres.

I use standard sizes brakes with ferredo brake pads and iam satisfied with that, i dont drive so fast :-)

In my opinion the Compact needs to be a little bit soft in the rear, and have a bit of spring travel also, then i doest feel so heavy in the front when it jumps.

Hope you kan understand my English writting.

Cheers Adam. I've spoken to David Masters at Bilstein since posting and he is going to sort something out with Eibach to try and keep my standard height and setup some front struts for me.

Bar the first 12 car we did with the 316i when the front nose dived on a very bumpy approach to a junction under braking it's never bottomed so I like the standard height.

Once the Ti is up and running I'll probably do some experimenting with different standard springs on the 316i so we can get some idea on ride heights against each spring.

I got them from the Bilstein online catalogue at http://web1.carparts-cat.com/default.aspx?11=18&14=4&10=4944264A110F44CC8637A60B5FCA4013018004&12=100

However when I spoke to David Masters he said he would do something else for the front anyway, I'm waiting on prices on them and springs at the moment.

The £250 scrapper Ti is about to go up in value dramatically I think.

Hi Claus, I very rarely go fast enough to make them jump anyway. Probably why my navigator shouts at me so much!

Your English is certainly a lot more clear than any attempt at Danish on my part would be.

Do you run on tarmac or forestry?

The car I am building is for road rallies. In the UK these are a mixture of tarmac public roads and farm tracks so we need to run a bit of a compromise setup to compensate for both.

Any other options on a supplier if I don't want to go adjustable? Or am I just going to have to bite the bullet and go adjustable?

Getting no joy out of Bilstein after waiting for them to sort something since the 13th of May so need to find someone else. I know a few of you have had excellent service from them but I'm just getting promises of phone calls back and them not bothering , I haven't even got a price yet let alone an idea of when I can expect a delivery.

PDL will do you a re-valved bilstein setup,, he cuts threads onto the casings and converts them to 2.25" coilovers for around £1k
I have also spoken with Nigel @Avo, they do a coilover kit which has a 40mm monotube front strut with adjustable dampening on both dampers for around £1k area

Hopefully should get my Gaz onto the car in the next couple of weeks.

I'm looking to order top mounts today or tomorrow. Are standard M3 top mounts a direct fit onto the compact? Also what's the view on bottom arm bushes? Powerflex or go for E36 M3 ones?

Sacked Bilstein off all together as although I know a lot of people have good results from David Masters frankly he didn't seem like he could be arsed to help in the slightest and after 5 or 6 weeks I didn't even have a price never mind a delivery date. Gaz couldn't be more helpful, answer straight away and delivered when they said they would.

When the Mk2 is running that's getting Gaz too, Bilstein can go forth from now on frankly.

Sounds similar to our dealings with bilstein, think its a case of if he got a jump the night before or not , is the level of "arsed" he can be !! We must have caught him on a good day :lol: daishag uses gaz and for single venue stuff seems ok..

How have you found the gaz shocks, I'm currently looking at them as a option for road rallying. So far found gaz to be helpful. And the price seems good.
