Ride Heights

[titan]

Righto, I've done the tried and tested approach...18x9 TD with 265/35 tyres all round, 20mm spacer at the rear. In terms of meeting the width of the arches, works extremely well.

I noticed UB has a lower rideheight than myself, my height was set at simpsons as a starting point to clear speedbumps etc and allow for drop. Although perhaps a daft point to add, I think the car would look better if dropped further and since the intrax allows for this easily, why not ?





Anyone got any opinions on this? I've no rubbing issues currently and the suspension is set very soft indeed. Does look like there is scope for going a bit lower, but wondered if anyone found it a driving benefit?

Sort of an open question really as depends again what you want out the car.

I would guess that running lower would help on most UK circuits ESP airfield ones but for the road and the Ring it will need you to run stiffer damping and maybe stiffer springs and I think this will slow you down and make the ride worse

Mine is on the same wheel set up but with KWV3 and looks a fare bit lower than yours. Well from the pictures away. It was dropped buy 20mm and it does rub at the front, but only very slightly on full lock and also when the dampers are full compressed right in the middle of rear part of the wheel arch. but it really is minimal. Currently at -2 neg at the front i am go to fit top mounts to go out to -3 for the track and i'm hoping this will stop all the rubbing.

FYI Titan, I've settled on 643 front and 640 rear ride heights. I think that's measured from top of arch by Simpsons and I am on Intrax as well. Thats not ultra low but no rubbing road or track.

What are your offsets Lee?

I ran TD 18x9 in both 20 and 30 offset

On same ride heights the 20 caught on the rear outer arch on fast track use.

I did not specify a set ride height, I just used my man Chris @ centre gravity (who is the best geo guy I think about), he corner weighted and dialled in my settings, it was a tad lower than yours iirc.

I also noted that other set-ups where lower rear to front, my car had more rake the other way, which is open to personal preference.

My advice try it yourself, change heights- one mans perfect set-up is shit for another.

ET30 and 20mm spacers at the rear, seems perfect from the point of filling the width of the arches. I can only imagine ET20 would need some serious camber to squeeze in, or rub ;-)

I think generally, if you lower the front too much you also need to stiffen it up and this introduces understeer.

I also increased the camber at the front this weekend (not tested on track yet, just the road) and found that in the dry its a more positive turn in, but in the wet understeers more. Clearly horses for courses in all conditions.

I'm running same stuff and similar set up as Shim. Set up again by Simpsons.

Titan, yours looks a little on the high side. If settings are very soft that won't be ideal for most UK tracks. Try stiffer settings and ring Ant for recommendations. They'll be happy to help.

mine looks about the same and im going to drop it as its more track than road. would leave it be for road

You could place your booster cushion on your front tyres the gap is that big lol!

Cheers, thats useful. So I'm comparing apples with apples - from top of arch to wheel centre ?
