theindustrialist Posted August 24, 2014 Report Share Posted August 24, 2014 Greetings. I've recently purchased a US model B310 coupe. It runs and drives, but the body is in rough shape. I plan to leave it in a style similar to the Motorfix corollas. I'm planning on having the chassis of the B310 as close to the ground as possible.The intitial setup will be 155/55s on 14x6 280zx wheels. I'll space the rears and have either RCA or NCRCA up front.Up front I'll be running modified function form coilovers, with the lower perch welded to the B310 strut body.This is the setup I currently have: The car with the above coilovers installed: In back I originally planned cut springs and shorter rear shocks, however I'm wondering if the adjustable spring perch from AE86 rear coil overs will work in the B310 chassis? 1 Quote Link to comment

Those coil overs would also fit a 1 1/2" shorter 280zx or Maxima strut which would give you a monster caliper and vented rotor up grade as well. You choice of zx 14"s will give lots of clearance for the rotors. I'm running S110 200sx 14" factory mags. Here's what the Maxima calipers look like on my 710... What spring rate are those fronts? Because you'll want to get somewhere near the same for the rears. You can cut the rear springs. This will lower and stiffen the stock spring but don't cut indiscriminately and wish you had cut less. There are formulas for working out how much. Cutting springs to set the ride height is wrong, it will lower, but you may find the rate increased way beyond what you want to drive on. If this is the case shorter but stiffer springs will be needed. Or like you say a coil over on the shock with the proper spring rate. Quote Link to comment
theindustrialist Posted August 24, 2014 Author Report Share Posted August 24, 2014 I may want to run 13" down the road, so for my goals I decided to stick with the OE brakes. The fronts are 6K or 335ftlb springs. I was planning to cut 1/2 coil or 1 coil at a time and get shorter rear shocks. Ideally I'd like to have an adjustable perch setup like this, which is the AE86 setup I was referring to: Quote Link to comment
datzenmike Posted August 24, 2014 Report Share Posted August 24, 2014 335 lb/in!!!!! on a light 310??? Racing 510s barely get over 300. Well whatever, but 225-275 is likely better suited. I'm running 150 and that's quite firm compared to stock 100. Yes, most go higher but over 300 on a street car? Seems over kill but you're young and can handle it. I'm old and like more comefort. I would start lower and work up. Like the rear coils you pictured. Buy the rate you want and then set the ride height. Cutting coils is guess work. You don't know in advance what the results are. 1 Quote Link to comment
theindustrialist Posted August 24, 2014 Author Report Share Posted August 24, 2014 I agree with cutting being a guestimate, however I haven't found anywhere selling rear AE86 perches directly; I may have to contact stance/ksport/megan/etc to see if I can purchase some, or perhaps find some used. 6K springs are what came with the function forms when I purchased them; if they prove to be too stiff I can purchase a pair of swift springs in whatever spring rate I want :) Quote Link to comment
Nascarkeith Posted August 25, 2014 Report Share Posted August 25, 2014 Welcome to the club. I just got a 310 about 3 weeks ago. I really want to lower mine as well. However, I only paid $400 for it so I don't want to have more in suspension parts than I do the car. I'm looking at just cutting springs or lowering the spring perch. I'm 6'3 and sit nice and low in the car with stock seats. Post some picks of your ride. Quote Link to comment
mrmark Posted August 25, 2014 Report Share Posted August 25, 2014 This is mine right after i bought it, too low for me. The tires rubbed like crazy and the header was damn low as well. Quote Link to comment
floyd17 Posted August 27, 2014 Report Share Posted August 27, 2014 This is mine right after i bought it, too low for me. The tires rubbed like crazy and the header was damn low as well. that's where i wanna go with mine... may need to roll fenders or cut and do flares.. 1 Quote Link to comment
theindustrialist Posted October 21, 2014 Author Report Share Posted October 21, 2014 The DC2 Integra coilovers I was running were too short, and wouldn't provide enough thread engagement in the lower mount. New CG Accord coilovers were ordered and paired with some 9K swift springs I had laying around, and I also got new calipers, rotors, balljoints, sway bar endlinks, tie rod ends, and T3 RCA. The rear has Mustang II Monroes and cut springs. The car is now drivable, but needs a few small tweaks and an alignment. Hopefully I'll drive and work on it more in the near future.Final height on 155/55/14. Definitely a ratsun. 4 Quote Link to comment
thatdirtykid Posted October 21, 2014 Report Share Posted October 21, 2014 In for more. I am all for people pushing the limits well beyond where I would. Since its not mine to drive all I care is you make it look bitching. Quote Link to comment

Tire rub means the rims were wrong for the car. With proper offset/width rims/tires should and can clear. I have a problem with making the car fit the rims. Should always be the other way round. 1 Quote Link to comment
dukerollo Posted February 22, 2015 Report Share Posted February 22, 2015 I likes it. Do you have any full on side shots of it that low? Quote Link to comment
