Seight Suspension "Correct" set up


Badger56

Recommended Posts

Does anyone have any recommendations for getting the suspension on my newly acquired Seight sorted properly, I don't think it's something I want to tackle myself and I think it's been "tinkered" with in the past by a keen but untalented amature. One tell tale is that the offside rear wheel catches on the arch (very slightly though) and the near side doesn't.  It's on TSW 7 x 17's with low profile tyres so not a lot of room in the arches obviously. 

 

I live within five miles of the factory so maybe they should be my first port of call?

 

Thanks

Dave

I'd thoroghly recommend Blink Motorsport ( http://www.blinkmotorsport.com/  ) in Cheshire, which should only be an hours drive for you.

 

They're members on here too, just search for some of their results etc

Thanks for the replies guys, I'll look into both of these.

 

Cheers

For completeness, Northampton Motorsport won't be a million miles from you either!

The thing is, while basic set up sheets do exist for most of the recent at least, Westfield models. Really, they should be regarded as just a starting point, in many cases.

What you need is a specialist, and all those mentioned above have the know.edge and expertise to do it, who will understand what they need to do to get the car feeling right for YOU. Everyone has different tastes and expectations, and everyone tend to use the cars slightly differently.

Some may prefer quite a loose, darty feeling car, whereas others want something more neutral. A specialist will know how to achieve this.

only 1 place to go that's Adam at Clear R motorsport.

might be a little too far as he is near Preston, would be worth it though...

My SeiGHT did that as well, it was the 225 wide 888 rear tyres catching on the inner lip of the rear arch, your wheel offset could also be a contributing factor

One thing that is worth mentioning and im sure would vastly improve how it drives is to ditch those 17' wheels! They have no place on a westy imo, take advice from some of the suspension setup companies mentioned but i would guess 15's would be much more suitable.

You'll be feeling every stone chipping on the road with 17" rims,  15"  with 50 aspect tyres is a well proven road wheel set up and 13" with 60 aspect for the track.   My guess is the 17" wheels make it for a choppy ride.

Also if you have very old yellow Spax shocks, they will make things even worse.    Most members rate Procomp, Blink, Northampton MS and the new kid on the block, Adam of CleaR for their Geo set ups and advise is free.

You would have a problem setting the car up properly on 13" wheels if it has underslung exhausts I should think! If it is side exhausts of course that is different.

Seem to remember many were supplied from the factory on 16" wheels for that very reason. And handling perfectly well.

Thanks again guys, I do have the underslung exhaust so I suppose 13's could be an issue, I'll get it looked at professionally and take advice, I think this just proves I was right not to have a go myself :-) 

 

The 17's do look lovely but I'm not precious about them if it would be better on a smaller diameter.

Well with an underslung exhaust I would think 13" rims would be a non-starter. You might get away with 15" rims, depending on tyre profile. On 4 cars with side exhausts and for road use it is a popular choice, and gives you a reasonable range/choice of trackday type tyres.

As Dave says, for road use with underslung exhaust, the factory used to recommend 16" rims, AFAIK. The reason is, and at the risk of over-simplifying it, to get the correct front suspension geometry you aim to have the front lower wishbones more or less parallel with the ground, and the rear of the chassis 20mm. or so higher than the front. If you did that with an underslung exhaust, using for example 13"x215/55 tyres you would have the exhaust almost dragging along the road!

I am on 15 inch and 205/50 tyres with an underslung exhaust and it works fine. I wont say I drive actively at speedbumps but its usually the gearbox hoop that is lowest point. i dont think you will get 13 to work well as above and also many Seights have larger brakes which preclude some 13inch wheels unless you choose calipers and wheels with care.

15 inch gives you a wide choice of rubber for track tyres and some nice soft ones to harness the torque too - at the expense of wear but who cares when the car does a few thousand miles a year?

I have used NMS and Blink and happy to go back to both - you wont regret a good set up, it will make you love your car again :-)

I'm running 15s on mine at the moment but with two up it does tend to ground the exhaust if driven too spiritedly on lumpy/heavily crowned roads. I am thinking of moving to 16s to gain a little more clearance without affecting the geometry.

I've used NMS for my set-up and have been very happy with the service and results.

 

Luke.
