150SV Posted August 22, 2023 Share Posted August 22, 2023 Whilst I love my 7, I do feel the ride quality could be improved without upsetting the rest of the cars dynamics.I am speaking to Simon at Meteor today to see what his suggestions are, but I wondered what others have tried/considered and why ?Personally, I feel the car should be able to ride the bumps better than mine currently does, and I dont really have enough experience in 7s to know if thats how they are ?My impressions are that it feels either poorly or over damped, it feels like it crashes over bumps, or bounces around on the top of them.

SM25T Posted August 22, 2023 Share Posted August 22, 2023 I fitted Protech one way adjustable dampers and new springs from ProComp Motorsport to my SV. They revalved the dampers to suit the 7. Front springs 300lb rears 185lb linear. Considerably cheaper than other options Link to comment Share on other sites More sharing options...
revilla Posted August 22, 2023 Share Posted August 22, 2023 I fitted refurbished original Bilstein dampers. I haven't really got much experience of others to compare with, but I can't see anything wrong with the way it rides and handles on the road.I took an Elise owner out for a spin yesterday and the ride quality was one thing that really impressed him.

Graham Hutton Posted August 22, 2023 Share Posted August 22, 2023 I've got the CORE one way adjustables on my SV from Meteor and they are great. The front with the digressive piston option feels terrific, much less crashy but still stiff for the track day. The rear is better than the bilsteins but it took a bit of experimenting before I found a damper setting I liked. He put softer springs on the front of mine but similar ones on the rear. I can't remember the rating to be honest but it was great on the way to brands hatch and great on the track too.I think the ride height/corner weight settings are important too. I have 15" wheels and about 85mm clearance under the sump and 10 to 15mm rake. Feels fab every time I drive it :-) Link to comment Share on other sites More sharing options...
Drakman Posted August 22, 2023 Share Posted August 22, 2023 Hello Graham, I am currently having my 7 flat floor/corner weighed and wheel alignment done as we speak. 85 mm under the sump sounds low to me but i have been measuring my ride height from the bottom chassis tubes to the ground, 135 front and 150 rear. My car has 13" wheels and has a wet sump so hangs lower than a dry sump, i can see that the lowest part is the sump but i haven't measured it there. Do you know what your ride height, measured from under the chassis tubes to the ground is?CheersDaveI should add my car has Bilstein 620R shock absorbers now fitted with 250 lbs front springs and 215 lbs rear springs. I found the 350 lbs std 620R springs were a little too harsh over some of the roads here in Australia. Link to comment Share on other sites More sharing options...
Tom_Arundel Posted August 22, 2023 Share Posted August 22, 2023 What tyres and pressures are you using? Link to comment Share on other sites More sharing options...
SM25T Posted August 23, 2023 Share Posted August 23, 2023 Do ensure that any ride heights are measured with the equivalent of driver (and passenger if carried) weights in the car.85mm under the sump is pretty luxurious for a k-series. Link to comment Share on other sites More sharing options...
150SV Posted August 23, 2023 Author Share Posted August 23, 2023 Grahamthats the setup I'm cconsiderinf....digressive fronts and progressive springs at the rear.... Link to comment Share on other sites More sharing options...
Graham Hutton Posted August 23, 2023 Share Posted August 23, 2023 I think my ride height from chassis rail is about 110mm at the front but will go and check tonight. I run the ZZS tyres with 16psi btw.The digressive fronts are terrific! Link to comment Share on other sites More sharing options...
ChrisC Posted August 23, 2023 Share Posted August 23, 2023 I would start with making sure the setup is correct and all components are functioning correctly before upgrading. So basically getting a flat floor setup and any bump steer issues resolved, then evaluate the need for an upgrade. Link to comment Share on other sites More sharing options...
Drakman Posted August 23, 2023 Share Posted August 23, 2023 I'm running Avon ZZS's at 18 psi. Link to comment Share on other sites More sharing options...

Simon.Rogers Posted August 23, 2023 Share Posted August 23, 2023 Hi DrakemanYou want to try some 130/140 0r max 150lb springs on your car.You won't believe the improvement. 215 is way over sprung. IMHO. Link to comment Share on other sites More sharing options...
Drakman Posted August 23, 2023 Share Posted August 23, 2023 Hi Simon,Thank you for the advice, would i also need to have the shocks re valved. My shocks are standard 620r Bilsteins that came std with 350 lbs springs, i was a little concerned dropping down to the 250 lbs fronts and the 215 rears.My 7 is a 2014 Roadsport Duratec 175. with front and rear ARB's and a drexler LSD. if that makes any difference. I figure your input would be very welcome in suspension matters.CheersDave Link to comment Share on other sites More sharing options...
Simon.Rogers Posted August 23, 2023 Share Posted August 23, 2023 Your dampers will be much much closer to optimal with the 150lb spring. 9" x 2.25"you are just over sprung currently.in the UK only Bilstein can service and revalve their own dampers.
