BC Coilover Setup Help

[Willo]

MickPM supplied and fitted some brand new BC coilovers a couple of months back for me and I have to say I'm loving them. (bargain price too ) I've been to Anglesey and Oulton with the Car since been fitted and can't believe how well the cars handles.

The only issue I have is the front wheel arches rub the tyres on hard cornering (Cascades at Oulton in particular). I've raised the front as much as is feasible but it still rubs. This may be a very stupid question as the answer seems obvious but would uprated springs help? - It already has uprated from standard BC setup). If so would there be any negative affect from uprated springs on the front?. I'm not arsed about comfort it only get driven to and from a track plus the occasional run out. Any other suggestions/ remedies also welcome of course

The car will be used for sprinting and I would expect places like Three Sisters and Aintree will see the arches fowl the tyres even more frequently than the aforementioned tracks so I' wanting to sort this before April.

I'm obviously going to give Mick a call to discuss (If he doesn't see this thread) as he seems a very level headed and knowledgable guy from the time I spent chatting with him whist he fitted but thought I'd get people opinions/ advise on here also.

Im sure that mick offers different spring rates for the BC coilovers.

Ill be looking at getting a set in the new year for my PH1 (not for track though)

You could look where they are actually rubbing and if it's the liners just let them rub through.. If it the wing then roll the lip out the way.

 

[marinemackay2003]

Check first where they are actually rubbing

May need more / less camber ect

Or maybe spacers

 

[Willo]

Ive removed the liners which helped but theyre rubbing pretty much in the centre of the arch. Will take a look to see what it is actually rubbing on now. Cheers.

Probably bumper brackets, bend them up and out of the way.

I think you're probably right actually. Will give it a go.... if youre right youll have saved me some time and money

Thanks

They take a bit of manipulating, arm yourself with a pair of mole grips, bend up and I'd put money on it resolving your issue.

Can't you add some more pre-load to the springs?

How would I do that?

 

[sbridgey]

I am guessing your BC's are like the ones I have on my mx5. The top rings are for pre load and the bottom is for ride height?

Ah right I'm not sure. Bottom are defo ride hight. Will take a look at that too. Thanks

 

[MicKPM]

You can add a set of pre - load springs chap but aren't you running 205 tyres to?

 

[Bobby.]

I bet it's rubbing where the 10mm bolt goes that holds the bumper on, all you need to do it cut the edge back to the hole, theirs about 5mm to cut back and then it won't rub.

Yes I am for sprints but does it with 195/50/15 A048s too

 

[MicKPM]

Ah right - I assume you've played with damping rate to? If you want to pop down one weekend I'll gladly have a proper look for you as I'm running the same as you without any scrub issues.

 

[Willo]

Thanks Mick, appreciate thst.

Ive altered the damping which helps but I dont want it to stiff for sprints. You need a good amount of damping on most circuits.

Its only on track I get it when giving it propper beans round the odd corner so dont think theres anything wrong. I know others with Bilsteins that have the same problem.

Will give the bending of brackets a go as advised above. Im really happy with the setup though

 

[MicKPM]

The offer is there chap so just let me know if you want to drop in. Thinking about it I don't run front section arch liners as I run brake cooling ducts and divertor plates. I pushed it extremely hard at Blyton recently and not a single bit of scrub which surprised me as I expected some from the rear at least due to the spacers and brackets.

Cheers mate.

Love Blyton, thats on the Sprint calendar again this year... hopefully ill make it there without my car catching fire this time.

 

[MicKPM]

Yeah i actually had more fun there than i thought i would. A properly quick little circuit, i was nearly touching 110 at Froids chasing Chi down in his R26. Glad to hear I'm not the only one that has issues there though... I blew my diff :-( #nemasis #circuit

 

[Willo]

Sounds like a good excuse to buy a gripper

 

[MicKPM]

Jesus not you aswell! LOL

Unfortunately I don't have that kind of money at the minute what with a holiday in April, a new workshop and the wife threatening another baby/house. I'm deffo going to squirrel some away though and may compromise on a Quaife if one turns up at the right price.

PMSL... Im really wanting one but struggling to justify the cost too. Could buy my car again for what one costs to buy and fit

 

[MicKPM]

Then it needs servicing because it's a plate diff... it's great and by far the best product of its type for the JB/JC box but the cost won't suddenly make me a better or less aggressive driver and as it's not a competition car lap times aren't a driving constraint.

 

[Willo]

At least if I havent got a LSD I can blame the car for my poor performances. If I keep improving the car there will be knowhere left for me to hide LOL

 

[MicKPM]

Because race driver!

 

[sprintcup]

I had the same issues, just put a big hammer to the bracket and lifted the ride height, stay open diff you now it makes sense, don't forget to put the plastic arch liners back in or I'll be talking to Mr Mansley lol :rasp:

Regards Russ....
