Deacon 1357 Report post Posted July 26, 2016 Another quick update. I was back at Moton yesterday. We softened the valving and dropped the rear spring to an 11kg to give 9f/11r. Seems pretty decent for a liveable street spec and good for bumpy track use. We've got a few clunks to try and eliminate and may try a freer flowing piston in the dampers too to soften them just a little more. 1 Ade reacted to this Share this post Link to post Share on other sites

Deacon 1357 Report post Posted July 30, 2016 Got chance to fit the cup 2's today. Only had chance to have a quick blast but wow. The Motons definitely like working with the cup 2's - the grip and handling is just bonkers. 2 Keethos and Ade reacted to this Share this post Link to post Share on other sites
Deacon 1357 Report post Posted August 12, 2016 Couple more bits arrived today. Big thank you to @James@Amber for the excellent service again. First are Perrin cam solenoid guards in red to match the other bits in the engine. Ordered these because my cam solenoid covers are suffering the rusting that seems so common and look unsightly so I wanted to do something about them. Not sure if the cam solenoid cover rust is a warranty issue? Second thing I was very lucky to get hold of - pretty sure this was the last set available new in the UK. Apologies for the dire picture - it's a Whiteline Roll Centre Correction kit which helps correct the geometry when the car is lowered Hoping to get the pads and roll centre kit fitted next week ahead of a couple of days at Curborough the week after when I can try out the Motons and Cup 2's properly. 2 James@Amber and Keethos reacted to this Share this post Link to post Share on other sites

It was recommended to me by someone who tracks their brz a lot and said it makes a big difference. Seems most useful if you're lowered over 30mm and 40mm is the sweet spot for me so I figured every little helps. Summit also make a kit with even more correction but it's also well over twice the price of the Whiteline kit and to be low enough to take advantage of the extra correction would also make you low enough to be not great on track anyway.

If you know of another kit hanging about let me know Best chance on another is probably a used one - I tried everywhere and could only find this last kit. The main symptoms is the extra roll that lowering produces because of the roll centre getting screwed up. The kit also sharpens the steering response up.

Jamie_GRMN 177 Report post Posted August 13, 2016 I had the white line kit fitted to mine when I dropped it on the BC's, was more of a precaution as I was lowering 40mm+. Can't say whether there was any specific improvement though as everything was done at once... i will say that the grease boots on the lower ball joints are shite, mine had split when I removed them to put the car back to standard after 20k ish, if you can refit the standard ones will be better 👍🏼 1 Deacon reacted to this Share this post Link to post Share on other sites

I'd have liked to have picked up the summit ones as they're a lot beefier but couldn't justify the over double cost. I'll see if I can get the boots swapped when they're fitted. 1 Jamie_GRMN reacted to this Share this post Link to post Share on other sites
Deacon 1357 Report post Posted August 25, 2016 I did two days at Curborough this week and so had a good chance to try out the Motons and Cup2's. The Motons faired very well - even with them only stiffened around 50% they were fantastic on track - I never had the issue I used to find on the flex a's of wanting to go stiffer but having run out of adjustment. They also meant I could happily attack the kerbs. The cup 2's were also very good - not as grippy as the federals as they're a harder compound but much gripper than the sport contact 5's I tried last time. They also held up really well to the 32 degree heat on Tuesday and were OK in the damp/wet today allowing me to beat the time I'd previously done on the sport contact 5's in the dry. 2 long-gone and Keethos reacted to this Share this post Link to post Share on other sites
Deacon 1357 Report post Posted August 31, 2016 Spent some time at Moton today. We've changed the springs to a 7kg front and an 8kg rear. I've only driven back from Moton but initial impressions are very positive. The lower spring rates also seem to be working the cup 2's better as I definitely felt there was a noticeable increase in grip. The dampers have also been dyno'd. I've attached the graphs below as they may be of interest to some people. Share this post Link to post Share on other sites
Mark@Abbey M/S 235 Report post Posted August 31, 2016 quite a big change in rebound with adjustment from minimum to maximum like most single adjustable dampers. What springs did the dampers get supplied with? Share this post Link to post Share on other sites

Deacon 1357 Report post Posted September 1, 2016 To give them a bit of a try me and Nikki took a spontaneous journey into Wales and put a couple of hundred miles on them today. We drove there with them set soft and back with a stiffer set up I thought would work well on track and wanted to try on the road (c6 r8 front and C4 r5 rear). The journey there was good. There is a little bit of low speed bobbling that still needs to be resolved but otherwise it was quite impressive - comfortable but firm I'd say - very well controlled. The journey back was much stiffer and bumpier. Not a set up I'd want to use for normal road use but liveable if you had to for some reason (can't have been that bad - Nikki slept for most of the return journey!) I think it'll work fairly well on track though. One of the effects of going down on the spring rate a little is that the cup 2's definitely seem to be working better - there is a noticeable improvement in grip. I think the previous set up was a little too stiff for the cup 2's and would work better with a stickier tyre and possibly aero. The other finding is fairly obvious - the car is definitely tracking the road better (it was good before, as those who attended the suspension meet and had a ride can confirm, but is better now). The bumpy b road performance has definitely improved and I'm fairly sure the track times (at least on the cup 2's and in my cars current configuration) will also have been improved too. It's taken a while but I think we are quite close now to a good fast road and very capable track set up. 2 Lauren and Tom B reacted to this Share this post Link to post Share on other sites
Mark@Abbey M/S 235 Report post Posted September 2, 2016 what ride height are you running? measured under the sill front and back (thin sill joint is best place to measure) Do you know what rear suspension travel you are running ans droop if you know it?

No idea on the rear travel or droop I'm afraid. Measured to the edge of the sill (not the thin sill joint the body edge) I measured 135mm front and 145mm rear. Why do you ask @Mark@Abbey M/S?

Why do you ask @Mark@Abbey M/S? these cars suffer from not enough rear suspension travel , you can jiggle most dampers around so you gain some travel back after lowering but you loose some droop which will cause issues when braking hard (dive) the rear dampers top out ( unable to droop anymore) can cause handling issues and lack of droop can make a car uncomfortable on a bumpy road. 1 Deacon reacted to this Share this post Link to post Share on other sites
