Sprint Fast road spring rates

Looking to go for the AVO fully adjustable set up from Jigsaw racing. Struggling with spring rates though.<br>
<br>
Car will ultimately be a fast road item with maybe the odd track day.<br>
<br>
Wish to keep my teeth in place for a bit longer so I was going to go with 330lbs fronts 175lb rears.<br>
<br>
Will my teeth survive such a setup!!!!!<br>
<br>
Also has anyone put bigger antiroll bars on front and rear to reduce roll.<br>
<br>
Ta<br>

Paul Patrickson was playing with double roll bar set ups a while back; don't think he's been on here for a while though...

bit fierce on the front for road I'd say, take it you're poly-bushing too...
<p>project orange - slow progress<br>
project black - coming on, could be sold...<br>
project white - pimp my tolly, next year!</p><i></i>

Yes poly bushing everything plus aluminium mounts for steering rack.<br>

Ian,<br>
<br>
I'd start by doing one thing at a time. Polybushing the whole car will make it feel a fair bit firmer anyway, as will the rack mounts. I'd try it with the bushes before going for anything else. I think the suggested order for changing suspension is:<br>
<br>
Bushes<br>
Anti Roll Bar<br>
Shocks<br>
Springs

Good point<br>
<br>
What options are there for the antirollbars?<br>

Anything....

stiffer than 200 and more than one inch lowered makes the car unsuitable for road use.<br>

Unsuitable for road use.

Can you expand a bit here. Why would it become unsuitable on the road - speed bumps, snappy handling etc?<br>
<br>
I look at my standard sprint set up and it looks like a drop of around a foot is in order. An exageration maybe but it just looks daft at the moment.<br>
Thanks<br>

Basically anything over an inch will ground the car on pretty much anything thicker than a penny. The car was designed with that much suspension in mind, and even 1" lower makes a really big difference to the handling. I think it also alters the front suspension geometry, putting the camber off and causing a bit of tramlining on bumpy roads. <br>
<br>
Running taller than standard (I think 75 profile) tyres will fill the wheelarches a bit better. But your best option is to use adjustable platfrom shocks, and screw them down which will compress the soft part of your spring first, increasing the spring rate and lowering the ride height at the same time.

Mine was lowered a good 3 inches, if not more.<br>
<br>
It was not safe - or driveable. Fortunately it never got out little damage was done! It was totally mental, subframe was almost touching the ground <!--EZCODE EMOTICON START : --><img src=

<br>
Hit a bump at speeds at that height and it'd hit the sump, rip off the manifold downpipe or worse....<br>
<br>
It looked this low:<br>

I have...

a 200 lb orange spring one inch lower car...<br>
Its fun and handles well, grounds on bad speed bumps and needs care and feels quite taught.<br>
The std cars I have are a bit softer and feel nicer but lean a bit. I wouldnt actually bother changing from std if everything esle is new/good.<br>
Triumph got a good comprompise with what they had at the time...<br>
I have several std dollies too and the Sprint wheels make the biggest difference.<br>

Gee. That is low. Not 3 inch for me then. Maybe 1 inch.<br>
<br>
I swear my sprint sits much higher than your your last photo. Maybe it has incorrect springs on it now.<br>
<br>
Thanks for the input.

<br>
If its come off a jack and hasn't move the front sits alot higher due to the wheels tucking under.
