Handling setup
Maybe wrong place to post?
Anyways Im trying to get my MAC1 setup. Have new 888's on the way. Been to Elite (in Essex) today to get all the wheels aligned.
Im going by what the guys at MAC have said. 1/2 degree neg camber and 3/4 degree toe in. When I told the people there they seemed shocked like that
was a big time no no.
Has anyone got any experience in this area. I got the wheels checked and have the readings but didnt want to get anything adjusted.
I wouldnt know if the handling was normal or bad due to my lack or knowledge on these but it certainly seems fine. I just want it setup for the new
tyres

I can't see why they appeared "shocked" at those settings,they might not be the best option for your car,or R888 tyres,but it would
handle fine on those settings.
But if your investing in some R888's,you must also must be thinking of doing a few trackdays,if thats the case,I have found the best settings
with my Indys running R888's for mainly on track,0.5 degrees tow in,2 to 3 degrees - front camber,1.5 to 2 degrees - rear camber,if your going
to use the car more on the road than track,then I would use the lower of the two camber settings,if mainly track use as mine was,then use the higher
of the two settings.

Ah cheers for that. I thought alot about tyres but from what I read it seemed the 888's were best suited for me. I will prob do about 6 or so
trackdays this year (thats about what id do on the roadbike) and enjoy some enthusiatic driving on road where I feel its safe(er)
Ill go more road biased as you said. Not sure if this will be a problem but they said I cannot adjust toe on back only camber. Its out and shows the
car will 'crab' to the right slightly but looking at tyres and driving I cant feel any problems??
Ignore the reds and greens as they just had a std road car setting. This is what mines at right now though so it def needs setting up!

Needs setting up yess, but it's not dire IMHO.
(Thinks I ought to get mine done!)
The rears can be shimmed on the hub mounts for toe.
Of interest/debate is the caster readings on the front and why they are varying so?

Yes as ReMan says you can shim the rears,its a fair bit of work though,but there's something going on with the caster there,should be around 6
degrees! this needs checking out first before getting anything else setup.

I understand camber and toe but not caster? What do I need to be checking or going back to Elite with?
As for back - guys at MAC said same thing about back. Can be done but from what I gather alot of work. Would it be noticeable/worthwhile in getting
this done.
Im getting quoted around £200 to have front and back setup to what I want as they need to remove ball joint adjust, re measure etc and its more time
consuming
Pleased to hear its not terrible though Reman. as said it doesnt feel bad to drive. A little light maybe at high speeds is about all ive noticed

I would expect the car to be a little unstable at high speed with the right front caster reading of just 1 degree caster,if they were both around the
same as the left side front,I dont think you would have such a big problem,not ideal,but it would at least be fairly stable with just over +3 degrees
on both sides,it may be a problem with the top wishbone ?,fitted wrong way round?,the problem you may have is the caster is not adjustable on the
Indy,not sure about your Mac1,as I don't known what set up you have on your car,but I would think its the same as the Indy,ideally you want to
end up with at least 5 degrees + caster, I would give Mac1 a call ask for there advice.

I found one of the biggest factors in my hand settings for lightness at speed was the ride height (attitude) front to back and tyre pressures
You don't mention anything on these?

Hi
The caster readings are way out. But every MAC#1 and MK indy i have setup have had simalar readings. Considering both manufacturers say they are
jigged to give 5 Deg you can see how far out the manufacturing is. Unless rose jointed it will need new wishbones making or have the originals
machined down and make them shim able within the brackets.
Re the other readings where they taken with you sat in the car. If not they are totally meaningless. I know they have set a number of cars up of the
kit variety without driver or equivelent weight on board. As REMAN suggests ride heights tyre pressures damper settings/balance etc ect unless all
these parameters are checked and set it's pointless. However unstableness at high speed and general light feeling to the steering is mainly down
to cater settings.
Cheers Matt

I am also shock ed at the suggested settings never use toe-out on a rwd car.

Toe-out is really for FWD cars. I have been told the following for RWD:
* a little bit of toe-in for stability (road use).
* a TINY bit of toe-out for quick steering (but this is really only for the track).
* straight-ahead/parallel for a compromise on the road.
I have mine parallel, which is a setup I like.

Hi
For £200 i would be wanting more than just a quick alignment setup done. What about corner weights and dampers and springs being tested and dynoed.
Cheers Matt

I know i thought 200 seemed a fair wack. They said it was the labour due to work involved get joint on/off etc. As for suspension height. Havn't
a clue but will speak to guys at mac about this and other settings mentioned earlier. Suspension settings ie are what mac rec. Off top of my head i
think it was 7 clicks out rear 4 front but tbh thats a personal thing as to how you like your ride. Tyre pressures were rec. On here at 18psi all
round so i've stuck at that and it seems good. They were 26 when i got it so i noticed a big difference in grip! Again thanks for all the input.
Its helped massively as i've learnt my way around my mac.

I would say Elite direct or most other tyre and exhaust centres would not be the best place to have your seven type car set up correctly,they may be
ok for setting a standard road car up,I am sure Matt at Procomp would do you a good deal on a full car setup,for around the same sort of money,it
would be a bit of a drive for you,but worth it

Yes I agree David with all the above,and your not going to go far wrong with parallel for a safe setup,but I am not sure if you have sierra uprights
on your car,may be different set up with cortina upright if you have those fitted,but Ive not drove the cortina setup,but the ones Ive driven with
sierra uprights if I left them at parallel they always felt a bit unstable,you could either go 0.5 degree out,or 0.5 degree in,either would improve
the feeling over parallel,but found 0.5 tow in felt better for me.

Sounds good to me. Where is he located? I can get a trailer down no probs.
have you got a number or website?
Im hoping to get a day next week to get this all sorted - just find bloody work gets in the way!
I thought same about Elite. They seem v.good but had literally no experience with these cars

Just got my car back from Elite today with the Toyo's fitted.
Settings as a member on here and MAC said to go with. I had to say something as the handling and grip is unbelievable!
Didnt realise you could have that with road tyres. A big thanks for all help though Im very very pleased
