Anyone running spiders with nitrons and toyo's ?

[mph.52]

Help, I am at my wits end with the above combination fouling the n/s rear wheel arch and would appreciate anyone who has successfully used 16" spiders with nitrons and Toyo's on a pre facelift Chimp, letting me know of any similar problems experienced - and any solutions found!!

[jonjo]

What's the offset?

Yes I have spiders on a 93 car. No problems if you have a set of wheels (front & rears) and put them on the right way round. If you have sourced Cerb spiders they use all fronts BTW, and IIRC some of the 'indy' conversions use these with spacers.

If you have fouling of the wheel arch at the top, that means you are probably running the car too low or your chosen springs are too soft (its a combination thing) at the rear, which seems to be a common fad for some reason.

What's the deal with the long/strong springs you mention in your profile, Dave? I always reckoned the Chim would benefit from having a bit more suspension travel...

[spend]

Its not really for length of travel, mainly less chance of getting coil bound, and as Joo pointed out it does stop people setting the back too low. The 10" springs are only an option with Nitrons on the rear AFIK.

Quite a few people are now running @450/375 spring combinations and I cant recall anybody trying the stronger springs posting negative comments As a side note I think you will find Pasco is absolutely gob-smacked in the difference it has made to his cars handling.

Sorry, wasn't expressing myself too clearly there - sort of the same thing really - regardless whether the spring travel is limited by the bump stop or by coil/coil contact; the result is to be avoided if you want to stay out of the hedge...

I think the thing is with a lightweight, front engined car you're relying on making the most out of weight transfer to aid traction hence a soft back end, only there's not enough spring length or damping control to avoid it bottoming out on B-roads taken at speed, and then things tend to become a bit erm, lively...

TBH the biggest problems I found was the rebound with softer springs was impossible to control & that was what upset the car far more than anything else. Stiffer springs deflect less and reduce this rebound ( no leap frogging ).

Blimey, you must be to post on Xmas day!

Did the smaller tyres come?

You're going to have to cut the arch away, you know ...

[mph.52]

Yes to both, the 235x50x16's arrived and fitted and the problem is now worse than the 245x45x16's !! where the 245's just caught the very shoulder of the tread pattern with the inner edge of the wheel arch the 235's now catch a bit further down the side wall and more frequently.Have no idea what to try next.

I run 16" spiders.
Obviously mine are fitted under the superior body shape, but maybe the same applies.
The factory also supplied the same tyres as I run.
225/45 16 at the front on a 16" rear, and 245/45 16 at the rear on a 16" front wheel.

Are you running standard suspension or nitron's by chance. also any idea whether the (slightly fussy)facelift model had widened arches to accomodate 245 tyres?

I run AVO's, cant see the nitrons making any difference at all, it can only be the ride height maybe.

Check my profile for body shape!!!

Perhaps it would be usefull to try disconnecting one of the bolts on the coilovers and moving the wheels/suspension up and down to look at the amount of travel needed between normal ride height and the wheel arch. Then using spring compressors assess how much travel you have in the coilovers before they reach the bump stop, reconnect them to the wishbones and see where the tyre ends up. Only other thing I can think of is to harden the shocks and/or put larger bump stops onto the coilovers.

(I would echo the ride height comment. More travel = more time for wheel/suspension to decelerate before hitting the bump stop.)

p.s. could someone tell me where to find details on the spider conversion for the Chim? Cheers, Martin

I think Sportmotive do a spider conversion, Peninsular may also do one (they did the first IIRC).

I believe the factory sourced Ford 5 stud hubs for the first 10 official conversions , these were muted to be Jeep / transit / scorpio parts at various times. It would be nice to know which part is used as this question crops up quite frequently.

Sportmotive had one on Ebay last week!!!

By harden the shocks do you mean increase the spring rate or just turn the adjusters a couple of clicks to hard?

[Don1]

I too have this issue - spiders and nitrons. Was told it was to do with springs, but haven't had any time to find out more, so will be interested with this thread.... (no use, sorry!)

[jonjo]

Can't see how springs are fine with one combination and not with the spiders. As I asked earlier what are the relative offsets of the two wheel types? If they are different you may be able to correct it with a small spacer.

Jonjo, I have had the wheel / nitron combination for a couple of years without problems it has only been since I changed from SO2's to Toyos that the problem has arisen. also am not sure how to measure the offset?

[AntonyJ]

The spiders have the offset marked inside them.
