Upgrade Shocker!

17 posts in this topic

Ok, I may have mentioned to some of you I intended to upgrade my shocks. With the impending track-day in May approaching i need to get things underway to have it complete in time!

 

So the question is what should i be looking for, i am thinking Nitrons, but am not sure which as this seems to be the general consensus?

 

My criteria are

i would like to be able to adjust them for when on track plus id like to be able to lower the car at the front to improve the weight balance.

 

What are the views of MLOC?

 

Thanks

Paul

 

Ps i do have a budget (declared to the boss) so lets not go overboard!!

I agree with Russ. Talk to your supplier about spring rates though - if you go too hard on springs it will ruin it on the road.

Speak to Dave at seriously lotus, I bought mine from him and his advice was very good. Nitron shocks are really good, I'm in my 3rd set across a couple if cars and can't recommend them enough. If you drive the car more biased on the road you may want a slightly softer setup

 

Fast road 40mm

I ran 400lb, 475lb on my k series elise and it was such a nice setup on track and road

 

 

Track day 40mm

As dean says, too hard a spring rate and you could ruin B road driving but fantastic performance on track.

You do not want anything stiffer than 400 / 475. i would even consider 325 / 400. Its personal preference really. I like a little bit of roll to warn me when its getting near the limit. With stiffer springs there is no roll and warning.

Personally I think G has it bang on. If it were me I would be looking at 40ml Nitrons with 400/475 springs.

 

Martin what spring rates does Stripey have? What were the LSS rates do you know?

Dean, it now has 400 / 475 on Nitrons. The LSS were lighter than that. I cant remember the actual spring rates though.

i agree with all the opinions above

 

I have had

 

Niton Streets,

40mm NTRs

46mm NTRs

 

to be honest the streets were great for the road but a little soft for the track. I bought some second hand Hoffman spec 40mm NTR's with very high spring rates which were amazing on a dry track but very compromised in the wet and on the road. I now have a set of trackday spec 46mm NTR's which for me are perfect.

Ran Lotus Mortorsport Ohlins 36mm 325/450 for years so would be inclined to go with Martin. Currently run 46mm 450/550 and its not bad either so would think you'll be happy with what has been recommend so far either way.

I'm running Gaz gold pro's with 500/550 spring rates, Cant fault them...... Even surprised how well they ride on the road and more than good enough for me on the track.

The question you need to ask yourself is : what are you intending to do.

A few trackdays or a lot of trackdays, trackday car or touring car?

 

If you want to use your car for a few trackday, spirited drive, holiday and even commute. Very hard spring will be a little difficult to live with. If nitron is what you are after, the 2nd generation of street series with fast road spring might be good.

 

When i started to be more involved with trackdays, i got a set of fast road (something like 325/400) which was very good all around, b road were fine etc.

When i got way to involved with trackdays, i move to the race set up at the time 400/500 which i still use. It is ok in most condition but a poor tarmac, it reminds me the location of lombar vertebras... But, on track, it car is pretty good, especially when Miles drives it.

 

I am guessing the spring rates are different for S2 but, the questions are the same.

Bear in mind that track focus solutions are more expensive (ntr vs nss) and might require other modifications

 

Edit: forgot to mention, i also recently fitted a stiffed antiroll bar (7/8 rather than 3/4) and i found i can run soft a the front making the car less bumpy of the rumble stripes

I did this list last summer - mainly to decide what spring rates to get for a Honda'd S2 running 46 Nitrons.

Slight thread high jack here but fentuz how do you find the 400/500 spring set up on damp/wet B roads?
